About Piroxicam-d3

Vaqora Chemicals supplies Piroxicam-d3, a stable isotope labelled analogue related to Piroxicam registered under CAS number 942047-64-5. Its molecular formula is C15H13N3O4S and its molecular weight is 334.4 g/mol. The IUPAC name is 4-hydroxy-1,1-dioxo-N-pyridin-2-yl-2-(trideuteriomethyl)-1lambda6,2-benzothiazine-3-carboxamide. It is also known as Piroxicam D3 (N-methyl D3) or PiroxicamED3.

The product is provided 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 Piroxicam-d3 in 10 mg, 25 mg, 50 mg and 100 mg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
