Batches are supplied with a certificate of analysis, and the supporting spectra can be sent ahead of a purchase order so your QA team can review them. They are bought for system suitability, peak identification, quantitation against limits and the impurity justification sections of regulatory submissions.

Questions
Flumazenil impurities, answered
What Flumazenil reference materials are available?
The catalogue currently lists 6 compounds for Flumazenil, including 5 pharmacopoeial impurities. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Flumazenil impurity standard?
A certificate of analysis travels with every lot. On request we share the characterisation set, usually 1H-NMR, mass spectrum, HPLC purity and IR, and for some materials TGA or water content. Ask for the data before ordering if your QA team needs to review it.
Can Zemixal make a Flumazenil impurity that is not listed?
Often yes. Send the structure, name or CAS number with the quantity you need and our sourcing team checks custom synthesis options, usually from 10 mg up to gram scale, with a quoted lead time.
