Chemical Structure

2-[2-(4-chlorophenyl)-4-phenyl-1,3-thiazol-5-yl]ethanoate 2-[2-(4-chlorophenyl)-4-phenyl-5-thiazolyl]acetate 23821-72-9 A816923 CAS 23821-72-9 chemical structure

Description

2-[2-(4-chlorophenyl)-4-phenyl-1,3-thiazol-5-yl]ethanoate 2-[2-(4-chlorophenyl)-4-phenyl-5-thiazolyl]acetate 23821-72-9 A816923 (C17H12ClNO2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
