Custom sourcing for fine chemicals and intermediates.

We support custom sourcing for fine chemicals, intermediates and project-based procurement requirements. Whether you need small-batch quantities, mixed-batch orders or specific documentation, we can help.

01

What is CAS-based sourcing?

Buyers specify requirements by CAS Registry Number, eliminating ambiguity across trade names and languages.

  • Unique identifier per chemical substance
  • Exact molecular match before pricing
  • Specification confirmed, then quotation
  • Full documentation tied to verified CAS

Assigned by the American Chemical Society.

02

What is small-batch chemical supply?

Procurement of fine chemicals in 1-50 kg quantities, below standard industrial minimums.

  • R&D labs: process development samples
  • Pharma: pilot batch validation
  • Formulators: test before bulk commit
  • Mixed-batch: multiple CAS in one shipment

Sample-then-bulk workflow supported.

Who uses our sourcing service?

  • R&D

    R&D chemists screening intermediates for new synthesis routes - need 1-5 kg samples with COA before internal approval

  • PM

    Procurement managers at mid-size manufacturers - access a vetted manufacturer network in China without managing each relationship directly

  • FM

    Formulators in cosmetics, coatings or agrochemicals - need mixed-batch orders across 3-5 CAS numbers in one shipment

  • TC

    Chemical trading companies - consolidate multi-CAS procurement through a single fine chemicals supplier in China

  • Lab

    University research labs - need specific intermediates in gram-to-kilogram quantities with proper documentation for grant compliance
