8-Chloro-2-phenyl-2,3-dihydrobenzo[b][1,4]thiazepin-4(5H)-one CAS 144934-96-3

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

8-Chloro-2-phenyl-2,3-dihydrobenzo[b][1,4]thiazepin-4(5H)-one (CAS 144934-96-3), molecular formula C15H12ClNOS and molecular weight 289.78 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 8-Chloro-2-phenyl-2,3-dihydrobenzo[b][1,4]thiazepin-4(5H)-one (C15H12ClNOS) 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 its high hydrophobicity (logP), 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).

CATO manufactures 8-Chloro-2-phenyl-2,3-dihydrobenzo[b][1,4]thiazepin-4(5H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
