Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 271.13 g/mol gives 5-Bromobenzothiophene-2-carboxylic Acid Methyl Ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Bromobenzothiophene-2-carboxylic Acid Methyl Ester (CAS 7312-11-0), molecular formula C10H7BrO2S and molecular weight 271.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Bromobenzothiophene-2-carboxylic Acid Methyl Ester (C10H7BrO2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-Bromobenzothiophene-2-carboxylic Acid Methyl Ester 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.
