Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (5-Bromobenzo[b]thiophen-2-yl)boronic acid.
(5-Bromobenzo[b]thiophen-2-yl)boronic acid (CAS 884010-25-7), molecular formula C8H6BBrO2S and molecular weight 256.91 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (5-Bromobenzo[b]thiophen-2-yl)boronic acid (C8H6BBrO2S) 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 the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-Bromobenzo[b]thiophen-2-yl)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.
