Chemical Structure
Description
The occurrence of 6-Hydroxy-2-[(2-methylphenyl)methylene]-3(2H)-benzofuranone is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Hydroxy-2-[(2-methylphenyl)methylene]-3(2H)-benzofuranone (CAS 620545-92-8), molecular formula C16H12O3 and molecular weight 252.26 g/mol, is a CATO reference standard with documented purity and traceability.
6-Hydroxy-2-[(2-methylphenyl)methylene]-3(2H)-benzofuranone (C16H12O3) 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 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
