Chemical Structure

4-(2-Chloroacetyl)-2H-benzo[b][1,4]thiazin-3(4H)-one CAS 68321-41-5 chemical structure

Description

The occurrence of 4-(2-Chloroacetyl)-2H-benzo[b][1,4]thiazin-3(4H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-(2-Chloroacetyl)-2H-benzo[b][1,4]thiazin-3(4H)-one (CAS 68321-41-5), a certified reference material (molecular formula C10H8ClNO2S, MW 241.69 g/mol) for analytical method development and quality control.

The molecular framework of 4-(2-Chloroacetyl)-2H-benzo[b][1,4]thiazin-3(4H)-one (C10H8ClNO2S) 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 its high hydrophobicity (logP), 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.

As a certified reference material (CRM), 4-(2-Chloroacetyl)-2H-benzo[b][1,4]thiazin-3(4H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
