Methyl 2-bromo-5-chlorothiazole-4-carboxylate CAS 1053655-63-2

Description

Compared with other compounds in its class, the molecular weight of 256.50 g/mol gives Methyl 2-bromo-5-chlorothiazole-4-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Methyl 2-bromo-5-chlorothiazole-4-carboxylate (CAS 1053655-63-2), a certified reference material (molecular formula C5H3BrClNO2S, MW 256.50 g/mol) for analytical method development and quality control.

Methyl 2-bromo-5-chlorothiazole-4-carboxylate (C5H3BrClNO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

CATO manufactures Methyl 2-bromo-5-chlorothiazole-4-carboxylate 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.
