About Risedronic acid-d4

Risedronic acid-d4 (CAS 1035438-80-2) is a stable isotope labelled analogue related to Risedronic acid offered by Vaqora Chemicals. With the molecular formula C7H11NO7P2, it has a molar mass of 287.14 g/mol. The IUPAC name is [1-hydroxy-1-phosphono-2-(2,4,5,6-tetradeuterio-3-pyridinyl)ethyl]phosphonic acid. It is also known as Risedronic Acid-d4 (Major).

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. 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.

We offer Risedronic acid-d4 in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
