Chemical Structure
Description
The molecular framework of 5-Methylbenzo[d]thiazol-2(3H)-one, 97% (C8H7NOS) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 5-Methylbenzo[d]thiazol-2(3H)-one, 97% (CAS 40925-61-9), a certified reference material (molecular formula C8H7NOS, MW 165.21 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
