Chemical Structure
Description
CATO supplies 4-Bromo-2-chloro-5-methylthiazole (CAS 1782805-91-7), a certified reference material (molecular formula C4H3BrClNS, MW 212.50 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, chlorine/bromine substitution, 4-Bromo-2-chloro-5-methylthiazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 212.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 4-Bromo-2-chloro-5-methylthiazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
