Preparing an API RFQ

Identify the material by its full name, salt or hydrate form, and CAS number if available.

Include your required specification or pharmacopoeial standard, estimated quantity, destination market and preferred timeline.

List the documents you need for your internal review. Ask the supplier to confirm source, sample availability and commercial terms before you proceed.

Discuss your requirements

Comparing specifications

Compare the same material identity, salt form and specification version across quotations.

Review the stated assay basis, impurity limits, water content and particle-size requirements with your technical team.

A lower unit price does not by itself establish equivalence. Confirm test methods, packaging, delivery terms and which documents relate to the proposed batch.

Discuss your requirements

Reviewing supplier documents

Start with a specification, a relevant certificate of analysis and a safety data sheet, subject to availability.

Check that manufacturer identity, material identity, batch number and document dates are consistent. Request clarification where information is incomplete.

Regulatory files and site certificates relate to particular sources and markets. Their applicability must be confirmed for your request; this website does not imply that any specific registration is available.
