Chemical Structure
Description
4-Bromothiazol-2(3H)-one (CAS 1086381-71-6), molecular formula C3H2BrNOS and molecular weight 180.02 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Bromothiazol-2(3H)-one (C3H2BrNOS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-Bromothiazol-2(3H)-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.
