Description

Compared with other compounds in its class, the molecular weight of 187.17 g/mol gives 5-Acetyl-4-hydroxy-2h-1,3-thiazine-2,6(3h)-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 5-Acetyl-4-hydroxy-2h-1,3-thiazine-2,6(3h)-dione (CAS 91114-97-5), a certified reference material (molecular formula C6H5NO4S, MW 187.17 g/mol) for analytical method development and quality control.

Structurally, 5-Acetyl-4-hydroxy-2h-1,3-thiazine-2,6(3h)-dione (C6H5NO4S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 187.17 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.
