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 2-(3-Bromobenzylidene)-6-hydroxybenzofuran-3(2h)-one.
CATO supplies 2-(3-Bromobenzylidene)-6-hydroxybenzofuran-3(2h)-one (CAS 620545-90-6), a certified reference material (molecular formula C15H9BrO3, MW 317.13 g/mol) for analytical method development and quality control.
The molecular framework of 2-(3-Bromobenzylidene)-6-hydroxybenzofuran-3(2h)-one (C15H9BrO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic 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 2-(3-Bromobenzylidene)-6-hydroxybenzofuran-3(2h)-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.
