Chemical Structure
Description
CATO supplies 2-Chloro-4,5-dimethylthiazole (CAS 56355-41-0), a certified reference material (molecular formula C5H6ClNS, MW 147.63 g/mol) for analytical method development and quality control.
The molecular framework of 2-Chloro-4,5-dimethylthiazole (C5H6ClNS) is characterized by a nitrile group, sulfur-containing functionality, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
