Every standard comes with a certificate of analysis. Structure confirmation data, typically NMR, MS and chromatographic purity, is available on request. They are bought for system suitability, peak identification, quantitation against limits and the impurity justification sections of regulatory submissions.
By impurity type
Pharmacopoeial4EP, USP, BP or JP named impurities
Metabolites3Hydroxy, desmethyl and conjugated forms
Counts are based on product names. One compound can fall into more than one type.

Questions
Glycopyrronium impurities, answered
What Glycopyrronium reference materials are available?
The catalogue currently lists 11 compounds for Glycopyrronium, including 4 pharmacopoeial impurities and 3 metabolites or hydroxylated analogues. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Glycopyrronium 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 Glycopyrronium 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.
