Chemical Structure
Description
2-Methyl-1,3-benzothiazole-6-carboxylic acid 6941-28-2 8257AE C9H7NO2S (CAS 6941-28-2) is a high-purity analytical reference standard with the molecular formula C9H15NO2S and a molecular weight of 201.29 g/mol.
The molecular framework of 2-Methyl-1,3-benzothiazole-6-carboxylic acid 6941-28-2 8257AE C9H7NO2S (C9H15NO2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, 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. 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-Methyl-1,3-benzothiazole-6-carboxylic acid 6941-28-2 8257AE C9H7NO2S 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.
