Chemical Structure

5-Acetyl-4-bromothiophen-2-boronic acid CAS 1256346-41-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 248.89 g/mol gives 5-Acetyl-4-bromothiophen-2-boronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Acetyl-4-bromothiophen-2-boronic acid (CAS 1256346-41-4), molecular formula C6H6BBrO3S and molecular weight 248.89 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Acetyl-4-bromothiophen-2-boronic acid (C6H6BBrO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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-Acetyl-4-bromothiophen-2-boronic acid 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.
