Chemical Structure
Description
CATO supplies 2,5-Dibromo-4-methylthiazole (CAS 79247-78-2), a certified reference material (molecular formula C4H3Br2NS, MW 256.95 g/mol) for analytical method development and quality control.
The molecular framework of 2,5-Dibromo-4-methylthiazole (C4H3Br2NS) is characterized by a nitrile group, sulfur-containing functionality, 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
