Chemical Structure

2-(2-Chlorobenzylidene)benzofuran-3(2H)-one CAS 61370-64-7 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-(2-Chlorobenzylidene)benzofuran-3(2H)-one.

CATO supplies 2-(2-Chlorobenzylidene)benzofuran-3(2H)-one (CAS 61370-64-7), a certified reference material (molecular formula C15H9ClO2, MW 256.68 g/mol) for analytical method development and quality control.

2-(2-Chlorobenzylidene)benzofuran-3(2H)-one (C15H9ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 2-(2-Chlorobenzylidene)benzofuran-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.
