3-Bromo-5,6-dihydrobenzo[b]thiophen-7(4H)-one CAS 274925-56-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Bromo-5,6-dihydrobenzo[b]thiophen-7(4H)-one.

3-Bromo-5,6-dihydrobenzo[b]thiophen-7(4H)-one (CAS 274925-56-3), molecular formula C8H7BrOS and molecular weight 231.11 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Bromo-5,6-dihydrobenzo[b]thiophen-7(4H)-one (C8H7BrOS) is characterized by sulfur-containing functionality, 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).

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 3-Bromo-5,6-dihydrobenzo[b]thiophen-7(4H)-one 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.
