(E)-4-(2-(3,4-dichlorophenyl)hydrazono)-1-methyl-3,4-dihydro-1H-thieno[3,2-c][1,2]thiazine 2,2-dioxide CAS 477845-67-3 chemical structure

Description

(E)-4-(2-(3,4-dichlorophenyl)hydrazono)-1-methyl-3,4-dihydro-1H-thieno[3,2-c][1,2]thiazine 2,2-dioxide (CAS 477845-67-3), molecular formula C13H11Cl2N3O2S2 and molecular weight 376.28 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (E)-4-(2-(3,4-dichlorophenyl)hydrazono)-1-methyl-3,4-dihydro-1H-thieno[3,2-c][1,2]thiazine 2,2-dioxide (C13H11Cl2N3O2S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
