Chemical Structure
Description
(Z)-2-(4-Methylbenzylidene)benzofuran-3(2H)-one (C16H12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 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).
(Z)-2-(4-Methylbenzylidene)benzofuran-3(2H)-one (CAS 97871-89-1), molecular formula C16H12O2 and molecular weight 236.27 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
