Chemical Structure

Methyl 2-bromo-4-(trifluoromethyl)thiophene-3-carboxylate CAS 1853236-69-7 chemical structure

Description

Methyl 2-bromo-4-(trifluoromethyl)thiophene-3-carboxylate (CAS 1853236-69-7) is a high-purity analytical reference standard with the molecular formula C7H4BrF3O2S and a molecular weight of 289.07 g/mol.

Methyl 2-bromo-4-(trifluoromethyl)thiophene-3-carboxylate (C7H4BrF3O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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-4-(trifluoromethyl)thiophene-3-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.
