From a single spot purchase to a full delivery chain
All three partnership models share the same capability backbone: a governed supply network down to the base. The only difference is whether you already own the process. You can start with the smallest step — no need to bet on the entire chain up front.
Three partnership tiers, deepening step by step
Trust is staged: validate delivery discipline with the smallest order first, then move on to program development and tech transfer.
Best for: Have a defined CAS / spec / quantity
- Qualified-supplier screening & commercial terms
- Quality agreements & dossier documents
- Export, customs clearance & temperature-controlled delivery
- Dual-use items / ECCN pre-screening
Best for: Have a target molecule but lack a stable process or compliant capacity
- Route design & impurity attribution
- Pilot scale-up & process validation
- Analytical method development & transfer
- DMF / CEP document preparation
Best for: Need to land the process in your own capacity or a new region
- Full process package & analytical package transfer
- On-site scale-up support & validation batches
- Marketing authorization holder & license arrangements
- Long-term technical maintenance & iteration
Three capability layers form a non-replicable delivery discipline
Intelligence decides what to do, the supply network decides whether it can be done, and quality governance decides whether it can be done stably over the long term.
Working backward from blockbuster drugs and patent-expiry windows to the demand for key intermediates — we first say what to build, then talk supply. Every candidate runs a four-dimension screen (qualification × capacity × market × compliance) before entering the catalog.
Not a matchmaking directory, but a governed capacity network: specialty plants in chiral, fluorination, multi-step coupling, continuous-flow, etc. are classified and on record, each with an audit history, historical batches and a backup plan.
Quality agreements, change control, deviations & CAPA, full-batch COA traceability, plus PCF carbon-footprint data — this is where the coordinator's true technical assets lie.
Five coordination functions, one responsible entity
All five coordination functions are held by a single entity that plans and is accountable for the outcome — instead of you having to stitch five suppliers together.
Supplier screening & commercial terms: screened by qualification, capacity, export history and compliance record; commercial conditions folded into the master contract.
On-site audit & CAPA closure: audit findings and corrective actions are closed within the project — problems are not thrown back to the buyer.
Export, customs clearance & delivery: including dual-use items / ECCN pre-screening, cold chain and temperature-control documentation.
Route, impurity & scale-up: synthetic route evaluation, impurity attribution, scale-up and process validation.
DMF, CEP & filing documents: prepare CTD modules by target country and maintain across the lifecycle.
Unibest — one contract, one plan, one escalation window.
Chemistry capability on call
Process capabilities callable by route choiceThe following are stable capacities owned by group entities or already brought under governance agreements, matched to molecular difficulty — not sourced ad hoc from whoever is cheapest.
Asymmetric synthesis, enzymatic and crystallographic resolution are evaluated in parallel, compressing step count while preserving enantiomeric purity — suited to single-isomer intermediates.

Built on Shanghai Daoyi Zhenhe Biotechnology's lipid nanoparticle delivery capability, covering lipid formulation, encapsulation and lyophilization process development.
Four services covering the path from screening to scale-up
Beyond products, Unibest delivers technology and capacity as a service: CRO on R&D, CDMO on manufacturing, flow chemistry and mechanochemistry on process.
CRO Services

Flow Chemistry
↓ Flow ChemistryContinuous-flow microreactor development and scale-up for hazardous reactions and greener manufacturing — detailed below.
Mechanochemistry
Ball-milling and solvent-free mechanochemical routes: fewer steps, dramatically less solvent — the next stop for green processes.
Continuous-flow process platform
Intrinsically safer continuous process developmentMoving batch parameters onto continuous equipment unchanged is the most common way this route fails. The capabilities below are supported by Zhejiang Tize Pharmaceuticals; each is assessed per molecule and route before scheduling.
The biggest obstacle in shifting from batch vessels to continuous flow is thatbatch process parameters do not transfer to continuous processes. Hand the design to a team that builds equipment but knows neither organic chemistry nor reaction engineering, and production stays inefficient indefinitely.
Kinetic models plus AI surrogate models are used to design and optimize the reaction parameters of each continuous process, rather than moving batch parameters straight onto continuous equipment.
Four core technologies
A closed loop from safety boundary to parameter control to intelligent optimizationA very high surface-to-volume ratio and excellent heat removal keep in-line hazardous inventory and potential temperature rise low; the inherent flame resistance and explosion protection of piping turn formerly runaway-prone reactions into intrinsically safe processes.
Reaction-path analysis and AI fitting of experimental data build the kinetic model that governs selectivity; the influence of temperature and molar flow ratio on selectivity is simulated to derive high-selectivity parameters and tailor the process to specific continuous equipment.
For unclear mechanisms, multiphase catalysis and multi-objective multi-unit operations, AI surrogate statistical models led by Bayesian optimization complement the kinetic model — approaching the global optimum without fitting the function as a whole and returning a Pareto front.
In-line techniques such as ReactIR and Spinsolve NMR, combined with artificial neural networks, estimate reaction-component concentrations in real time for multi-step monitoring and push process optimization toward full automation.
Batch vessel vs continuous flow: intrinsic safety
Redesigning the process boundary of hazardous reactions around intrinsic safety| Aspect | Batch vessel | Continuous flow |
|---|---|---|
| Reaction volume | Large volume required, poor cooling | High surface-to-volume ratio, excellent heat removal |
| Hazardous inventory | High reactant concentration, large in-line inventory | High at the inlet, decreasing along the path, small in-line inventory |
| Reaction control | Only through reactor temperature | Excellent heat removal plus heat-dilution effect |
| Cooling failure | Emergency handling required | Inherent flame resistance of piping, strong explosion protection |
Measured gains in continuous synthesis
Reaction types with continuous capability
Hazardous and strongly exothermic reactions suited to continuous conversionThe figures above are measured values from existing projects under specific molecules and process conditions; they are not a commitment for any particular project. Suitability for continuous operation and the achievable gain must be assessed case by case.
Project delivery chain
Route design → scale-up → commercial supply · handled by the group's own CDMO basesNo change of contact across the chain: process, quality, regulatory and supply are advanced through a single project window.
Around the target molecule and project stage, we provide route assessment, compound preparation and technical coordination — for compounds not in the catalog.
As the project evolves, we engage process R&D, analytical methods and scale-up production resources until commercial readiness.
Quality control, impurity profile and regulatory documentation are advanced together; modules required for DMF / CEP are prepared by target market.
Continuous supply is secured through batch scheduling and backup capacity, reducing the stock-out risk of a single site and a single batch.
Complete transfer of process, analytical methods and documents between pilot and commercial bases, shortening the scale-up cycle.
A single project window connects the demand side with the group's R&D, manufacturing and research resources, reducing multi-party coordination.
Group growth path
Four phasesFrom chemical trading in Ningbo in 2003 to a group network spanning R&D, CDMO, formulations, green technology and global market platforms.
Chemical trading built the first customer and supply-chain base; the group then moved into pharma intermediates and new-material R&D.

How the capabilities empower each other
The group is not a flat collection of companies but a top-down empowerment chain: capital and governance provide the foundation, technology and process deliver scalable solutions, manufacturing and compliance carry out scale-up and registration, global platforms land products and rights in specific markets — and market requirements flow back into R&D.
Industrial investment, holding and team incentives provide long-term capital and a governance framework for the operating entities.
Capital empowerment·A single investment platform invests externally while operating entities focus on their own business.
Pharma intermediates and new-material R&D, combined with AI drug design, continuous flow and mechanochemistry, delivers scalable routes and reaction conditions.
Process & route empowerment·Tize's technology platform recommends candidate routes and reaction conditions to the CDMOs, reducing scale-up risk.
CDMO for chemical drugs and intermediates, API CDMO, formulation MAH and macromolecule LNP delivery — carrying scale-up and registration files.
Product & rights empowerment·Products and registration files from the manufacturing layer are landed by the global platforms.
Regional entities handle import, licensing, registration and commercialisation, landing products and rights in specific markets.
Market & regulatory feedback·Registration and quality requirements of target markets define the next steps for R&D and processes.
Guangzhou Taqing Environmental (LTS low-temperature supercritical technology, 2018) provides green process and waste-reduction solutions to every manufacturing base. It reaches into both the technology and the manufacturing layer rather than forming a layer of its own.
Entities and years are compiled from public disclosures; entries within a phase are ordered by year of entry. Shareholding ratios and intra-group transaction arrangements are not public information.
How the supply network is screened
Suppliers are not managed by a list but by a set of rules anyone can restate. Below are the three layers we verify, and the grounds on which we end a relationship — the rules are public, the names are not.
First: what kind of entity is it
The same quote can come from a lab, a plant or a trader — three entirely different risk and negotiation profiles. Classification comes first.
R&D Company
Molecule design and process development; can take early-stage custom synthesis
CDMO
Process development and scale-up, from grams to tonnes
Chemical Manufacturer
Base and fine chemical capacity — the main upstream source
Generics Manufacturer
Formulation lines and registration experience; may be supplier or customer
Trading Company
No own capacity; value is channel and consolidation — must be cross-checked against factory capability
Originator
Originator firms, usually appearing as the demand side
Then: what backs the claim
Official credentials are granted by third parties and outweigh self-description; capability tags separate those with capacity from those merely reselling.
Credentials
Capability tags
On top of repeated quotations and delivery records we run a staged capability assessment. The scores and their breakdown are commercially confidential — but the same standard applies to every candidate, including our own affiliated plants.
When we end a relationship — and when it can resume
Spelling out exit conditions is far more useful than the phrase “quality suppliers”: it gives partners a clear expectation and binds us to the same standard.
Grounds for termination
- No valid operating licence
- Sample failing functional tests repeatedly
- Price raised after order acceptance
- Process/product mismatch causing downstream failure
- Batch consistency cannot be guaranteed
Grounds for reinstatement
- Licences completed
- Samples re-validated and passing
- Pricing returned to a reasonable range
- Relationship restored and documented
- Original finding corrected as an error
