Chemical Structure
Description
6,7-Dimethylbenzo[d]thiazol-2(3H)-one, 97% (CAS 80689-21-0), molecular formula C9H9NOS and molecular weight 179.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6,7-Dimethylbenzo[d]thiazol-2(3H)-one, 97% (C9H9NOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 6,7-Dimethylbenzo[d]thiazol-2(3H)-one, 97% 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.
