About Meloxicam-d3

Meloxicam-d3 (CAS 942047-63-4) is a stable isotope labelled analogue related to Meloxicam offered by Vaqora Chemicals. With the molecular formula C14H13N3O4S2, it has a molar mass of 354.4 g/mol. The IUPAC name is 4-hydroxy-N-(5-methyl-1,3-thiazol-2-yl)-1,1-dioxo-2-(trideuteriomethyl)-1lambda6,2-benzothiazine-3-carboxamide. Common synonyms include Meloxicam D4 and Meloxicam D3 (2-methyl D3).

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. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

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. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

Vaqora Chemicals supplies Meloxicam-d3 in 10 mg, 25 mg, 50 mg and 100 mg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
