Impurity reference standards
Alprazolam impurity standards
This page brings together 5 Alprazolam related compounds that analytical teams use to identify, quantify and control impurities in the active ingredient and the finished dosage form. The range includes 2 isotope-labelled standards and 1 metabolite or hydroxylated analogue.

Every standard comes with a certificate of analysis. Structure confirmation data, typically NMR, MS and chromatographic purity, is available on request. Laboratories use them to validate related-substance methods, set specification limits under ICH Q3A and Q3B, and identify unknown peaks in stability samples.

Questions
Alprazolam impurities, answered
What Alprazolam reference materials are available?
The catalogue currently lists 5 compounds for Alprazolam, including 2 isotope-labelled standards and 1 metabolite or hydroxylated analogue. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Alprazolam 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 Alprazolam 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.
Are isotope-labelled Alprazolam standards available?
Yes. 2 stable-isotope labelled compounds are listed, suitable as internal standards for LC-MS bioanalysis and trace impurity quantitation.
