CATO supplies 3-(2,3-Dihydrobenzofuran-5-yl)-2-propenoic acid (CAS 198707-57-2), a certified reference material (molecular formula C11H10O3, MW 190.20 g/mol) for analytical method development and quality control.
3-(2,3-Dihydrobenzofuran-5-yl)-2-propenoic acid (C11H10O3) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
