2-((3-Chlorophenyl)amino)-4H-[1,3]thiazino[5,6-b]quinoxalin-4-one CAS 154371-18-3

Description

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.

2-((3-Chlorophenyl)amino)-4H-[1,3]thiazino[5,6-b]quinoxalin-4-one (CAS 154371-18-3), molecular formula C16H9ClN4OS and molecular weight 340.79 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-((3-Chlorophenyl)amino)-4H-[1,3]thiazino[5,6-b]quinoxalin-4-one (C16H9ClN4OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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 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.
