Chemical Structure
Description
(2-Hydroxy-4-(octyloxy)phenyl)(2-hydroxyphenyl)methanone (C21H26O4) contains a flavonoid core, a hydroxyl group, an ether linkage. 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.
