5-phenyl-2H-1,2,6-thiadiazine-3-carboxylic acid 1,1-dioxide CAS 91445-62-4 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 5-phenyl-2H-1,2,6-thiadiazine-3-carboxylic acid 1,1-dioxide.

5-phenyl-2H-1,2,6-thiadiazine-3-carboxylic acid 1,1-dioxide (CAS 91445-62-4), molecular formula C10H8N2O4S and molecular weight 252.25 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-phenyl-2H-1,2,6-thiadiazine-3-carboxylic acid 1,1-dioxide (C10H8N2O4S) contains 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 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 252.25 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
