Whether you are evaluating a synthetic building block or planning an industrial purchase, a shared specification helps both teams assess the same material.
Prepare my enquiryInclude the CAS number, chemical name and intended use. Specify an isomer, salt or hydrate form when it is relevant to your process.
Share your target assay, test method and limits for critical impurities, water or residual solvents. Attach your specification if available.
State the quantity, preferred packaging, destination and required delivery date. Ask for the quotation and supporting documents to be reviewed together.
04 / Sourcing questions
Enter the CAS number in the catalogue search. You can also search by English or Chinese name, synonyms or molecular formula where recorded. Open the product detail page to check its identity and category before sending an enquiry.
A catalogue entry identifies a material within our sourcing portfolio. Availability, price, minimum order quantity, grade and delivery schedule are confirmed for each enquiry. The catalogue does not publish live stock or a fixed commercial offer.
List the documents required by your team when submitting an enquiry. Ask for the current safety data sheet, a suitable specification and relevant analytical evidence. Document availability and the applicable batch must be confirmed for the proposed supply.
Send a sourcing enquiry with the product name, CAS number and target quantity. Include the intended application and any essential quality requirements so that the team can assess your request.
