01
Intermediate Sourcing
Check Chinese supplier availability for pharmaceutical intermediates, route intermediates, and medicinal chemistry building blocks.
China Sourcing Partner for MedChem Teams
Pharmaceutical intermediates & building blocks sourced from China.
We help overseas laboratories, biotech companies, CROs, and chemical distributors source hard-to-find small-molecule building blocks, pharmaceutical intermediates, and custom synthesis products from verified Chinese suppliers.
Send CAS numbers, structures, product names, required quantity, purity, and deadline. We check availability, documentation, lead time, and export feasibility before quotation.
Services
Practical sourcing support for research chemicals and intermediates.
Our work focuses on supplier screening, quotation comparison, document collection, and communication support for small-molecule chemistry projects.
02
Custom Synthesis Inquiry
For compounds without reliable stock, we help compare custom synthesis options, estimated lead time, and technical feasibility.
03
Documentation Support
Collect and organize COA, SDS, NMR, LCMS, packing information, and export-related documents when available.
Product Focus
Categories we can help investigate.
Best fit: stable, non-controlled, small-quantity, high-value research intermediates and building blocks.

Process
Clear steps from inquiry to quotation.
A simple RFQ workflow helps reduce back-and-forth and makes price, purity, lead time, and documentation easier to compare.
Send CAS, structure, or product name
Include quantity, purity requirement, project deadline, and destination country.
Availability and supplier screening
We check stock, custom synthesis possibility, supplier history, and basic compliance feasibility.
Quotation comparison
You receive available options with price, lead time, purity, package size, and documentation status.
Order and follow-up support
We coordinate communication, documents, shipment information, and after-sales follow-up where applicable.
Why Work With Us
Chemistry-background sourcing, not blind trading.
We understand organic synthesis, functional groups, salt forms, stereochemistry, purity documents, and the practical risks of hard-to-find small-molecule intermediates.
Best Use Case
Hard-to-find, small-quantity, urgent, or custom.
We are most useful when a compound is difficult to find, when multiple suppliers need to be compared, or when documentation and English communication need to be organized quickly.
Request for Quotation
Send us your CAS or structure.
Submit your RFQ directly through this form. We will review availability, documentation, lead time, and compliance before replying.
Compliance Notice
We do not support transactions involving controlled substances, illegal chemicals, explosive precursors, scheduled drug substances, or products restricted by applicable laws and regulations. All inquiries are subject to compliance screening before quotation and shipment.
