Chemical Structure
Description
The occurrence of (2-Oxodihydrofuran-3(2H)-ylidene)methyl benzoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (2-Oxodihydrofuran-3(2H)-ylidene)methyl benzoate (CAS 67194-27-8), a certified reference material (molecular formula C12H10O4, MW 218.21 g/mol) for analytical method development and quality control.
(2-Oxodihydrofuran-3(2H)-ylidene)methyl benzoate (C12H10O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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).
