About Midazolam D5

Midazolam D5 is a stable isotope labelled analogue related to Midazolam carrying the CAS registry number 395067-42-2. With the molecular formula C18H13ClFN3, it has a molar mass of 330.8 g/mol. Its systematic (IUPAC) name is 8-chloro-3,4,4-trideuterio-6-(3,5-dideuterio-2-fluorophenyl)-1-methylimidazo[1,5-a][1,4]benzodiazepine. Alternative names: Midazolam-d5 (Major) and Discontinued See M343003.

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. Good laboratory practice and suitable PPE are recommended during handling.

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 Midazolam D5 in 10 mg, 25 mg, 50 mg and 100 mg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
