Chemical Structure
Description
(Z)-2-(2-fluorobenzylidene)-6-hydroxy-7-methylbenzofuran-3(2H)-one (CAS 1092298-11-7) is a high-purity analytical reference standard with the molecular formula C16H11FO3 and a molecular weight of 270.26 g/mol.
(Z)-2-(2-fluorobenzylidene)-6-hydroxy-7-methylbenzofuran-3(2H)-one (C16H11FO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
