Questions
Buying for pharmaceutical manufacturing and QC
Can I buy an API and its pharmacopoeial impurities in one enquiry?
Yes. Add the API and the named impurities to the quote panel together. We confirm which impurity standards are available from stock, which need synthesis and what characterisation data comes with each, so your method validation and supply qualification can run in parallel.
Are excipients available alongside the active ingredient?
Common excipients such as microcrystalline cellulose, lactose monohydrate, povidone and magnesium stearate can be quoted with pharmacopoeial documentation where the producer supplies it. State the monograph and edition you work to, and the COA will report against it.
How do you handle solvents that are controlled precursors?
Some solvents and reagents used in drug synthesis are listed precursors in India or at destination. We flag these on the quotation and may ask for an end-use declaration or import permit before dispatch. Sharing your licence details early avoids delays.
