Chemical Structure
Description
2-(Chloromethyl)-3-methylbenzo[d]thiazol-3-ium chloride (CAS 92876-35-2), molecular formula C9H9ClNSCl and molecular weight 234.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(Chloromethyl)-3-methylbenzo[d]thiazol-3-ium chloride (C9H9ClNSCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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).
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.
CATO manufactures 2-(Chloromethyl)-3-methylbenzo[d]thiazol-3-ium chloride 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.
