CATO supplies 1431555-20-2 4-Bromo-3-chlorosulfonyl-5-trifluoromethyl-thiophene-2-carboxylic acid methyl ester MFCD24386171 (CAS 1431555-20-2), a certified reference material (molecular formula C7H3BrClF3O4S2, MW 387.58 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system, 1431555-20-2 4-Bromo-3-chlorosulfonyl-5-trifluoromethyl-thiophene-2-carboxylic acid methyl ester MFCD24386171 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 387.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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 1431555-20-2 4-Bromo-3-chlorosulfonyl-5-trifluoromethyl-thiophene-2-carboxylic acid methyl ester MFCD24386171 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.
