CDMO · Custom Synthesis · Contract Production
Custom synthesis, biosynthesis and contract production of pharmaceutical intermediates, electronic chemicals and specialty silicones, from kilogram samples to multi-ton supply. Every project runs under NDA.
We take molecules made to a customer's own specification from route review to steady supply, in three areas.
Our longest-running CDMO area: custom intermediates and building blocks made to the customer's route and specification.
Custom electronic solvents and capacitor electrolyte materials, made at a partner production base in Xinjiang that is dedicated to electronic chemicals. SUNCHEM handles the base's export sales.
Special silanes, siloxanes and silicone materials made to a customer's structure or performance target, for cases where a standard catalogue grade does not fit.
We run both classic chemical synthesis and biological routes. For chemistry not listed here, send us your route and we will check it with our partner facilities.
Fermentation and biocatalysis are where we are expanding our CDMO work. We take on projects where a biological route gives better selectivity or a cleaner process than chemical synthesis.
Every project follows the same five steps. Timing depends on the chemistry, so we confirm it per project.
SUNCHEM does not run every reaction under one roof. For each project we choose a qualified manufacturer with the right equipment, permits and experience for that chemistry. Where the volume justifies it, production runs in a workshop dedicated to the customer.
SUNCHEM stays your single point of contact. We manage the project and the technical exchange, handle COA / TDS / SDS, and coordinate export, so you do not have to deal with several factories yourself.
Most of our custom work is made for one customer and is not listed on this website. We sign an NDA before any technical exchange. We do not disclose customer names, structures or volumes to third parties, and we do not use a customer's project as a public case study without written consent.
If you need a molecule that is not in our catalogue, contact us anyway. That is what most CDMO enquiries look like.
A few examples cleared for public listing. They are a small part of our custom work.
| 제품 | CAS | 일반적인 사용 |
|---|---|---|
| 4-Chlorophthalic acid monosodium salt | 56047-23-5 | Intermediate for polyimide monomers and fine chemicals |
| Nitrosylsulfuric acid | 7782-78-7 | Diazotization and nitrosation reagent for dye and pharmaceutical synthesis |
| 2-(1,3-Benzothiazol-2-ylthio)succinic acid | 95154-01-1 | Corrosion inhibitor for coatings |
| 3-(Acryloyloxy)propyltrimethoxysilane | 4369-14-6 | Acrylate-functional silane coupling agent |
Specifications are agreed per project. TDS and SDS are available on request.
예. We sign an NDA before any technical exchange, and we can sign yours or provide ours.
From kilogram samples to multi-ton commercial supply. Each scale runs at a partner facility whose equipment suits the chemistry.
예. Most of our custom work is made for a single customer and is not listed publicly.
On the chemical side: nitration, Friedel–Crafts, halogenation (chlorination, bromination, fluorination), 에스테르화, hydrogenation, 산화, alkylation, amination and polymerization. On the biological side, which is our growing focus: microbial fermentation, enzymatic catalysis and whole-cell biotransformation. For other chemistry, send us your route and we will check whether it fits.
예. Fermentation and biosynthesis are a growing focus of our CDMO work. Send us the target molecule and specification, and tell us whether you already have a strain, an enzyme or a process, and we will assess the project.
A structure or CAS number, your target specification, the expected annual volume and, if you have one, your preferred route. Sample and quotation follow once we confirm feasibility.
We run projects through qualified partner manufacturers, using dedicated workshops where the volume justifies it. SUNCHEM manages the project, quality documents and export as your single contact.
Tell us what you need made: structure or CAS, 사양, 연간 볼륨. We reply by email about the NDA and next steps.
