Chemical Structure

Methyl-4-hydroxy-2-methyl-d3-2H-1,2-benzothiazine-3-carboxylate 1,1-Dioxide CAS 942047-62-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl-4-hydroxy-2-methyl-d3-2H-1,2-benzothiazine-3-carboxylate 1,1-Dioxide.

Methyl-4-hydroxy-2-methyl-d3-2H-1,2-benzothiazine-3-carboxylate 1,1-Dioxide (CAS 942047-62-3) is a high-purity analytical reference standard with the molecular formula C11H8D3NO5S and a molecular weight of 272.29 g/mol.

Structurally, Methyl-4-hydroxy-2-methyl-d3-2H-1,2-benzothiazine-3-carboxylate 1,1-Dioxide (C11H8D3NO5S) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 272.29 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
