FAQs

Do you supply both APIs and the impurity standards needed to test them?

Yes. Many buyers source an API and its related impurity or working standards together, which simplifies qualification. Availability of specific standards is confirmed per molecule.

Can you provide DMF or CEP support for APIs?

Where the manufacturing site holds a DMF, CEP or similar filing, a letter of access or copy can usually be arranged. We confirm this per product before quoting.

Are your solvents suitable for pharmaceutical QC?

HPLC, LC-MS and GC headspace grades are available with specifications suited to pharmacopoeial methods, and each batch ships with a COA and GHS SDS.

Which Incoterms do you offer to pharmaceutical buyers?

We offer EXW, FOB, CFR, CIF and DAP. Temperature-sensitive or small-quantity items usually move by air, while bulk APIs and solvents often move by sea.
