4-ethyl-2-methyl-thiazole-5-carbonyl chloride CAS 126889-03-0 chemical structure

Description

CATO supplies 4-ethyl-2-methyl-thiazole-5-carbonyl chloride (CAS 126889-03-0), a certified reference material (molecular formula C7H12ClNOS, MW 193.69 g/mol) for analytical method development and quality control.

4-ethyl-2-methyl-thiazole-5-carbonyl chloride (C7H12ClNOS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
