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. For nitrosamine risk evaluation, the N-nitroso standards allow confirmatory LC-MS testing against the acceptable intake limits.
By impurity type
Pharmacopoeial12EP, USP, BP or JP named impurities

Questions
Venlafaxine impurities, answered
What Venlafaxine reference materials are available?
The catalogue currently lists 34 compounds for Venlafaxine, including 12 pharmacopoeial impurities, 1 nitrosamine, 1 isotope-labelled standard, 6 metabolites or hydroxylated analogues and 3 degradation products. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Venlafaxine 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 Venlafaxine 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.
Do you supply Venlafaxine nitrosamine impurities?
Yes. 1 N-nitroso compound is listed for Venlafaxine. They are used for confirmatory testing and method validation in line with ICH M7 and the nitrosamine guidance from the major regulators.
Are isotope-labelled Venlafaxine standards available?
Yes. 1 stable-isotope labelled compound is listed, suitable as internal standards for LC-MS bioanalysis and trace impurity quantitation.
