Chemical Structure
Description
Owing to a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution, Methyl 2-(4-fluorophenyl)-4-(3-methoxyphenyl)-4-oxobutanoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
