About Clobazam-d5

Clobazam-d5 is a stable isotope labelled analogue related to Clobazam carrying the CAS registry number 129973-76-8. Formula C16H13ClN2O2, molecular weight 305.77 g/mol. Systematically, it is named 7-chloro-1-methyl-5-(2,3,4,5,6-pentadeuteriophenyl)-1,5-benzodiazepine-2,4-dione.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. Handle it with standard laboratory precautions and appropriate personal protective equipment.

Its mass shift relative to the unlabelled analyte makes it a dependable internal standard for LC-MS/MS assays, improving accuracy in bioanalysis, therapeutic drug monitoring and method validation. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

Vaqora Chemicals supplies Clobazam-d5 in 10 mg, 25 mg, 50 mg and 100 mg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
