Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 3-Mesityl-5-phenyl-4,5-dihydroisoxazole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 265.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO supplies 3-Mesityl-5-phenyl-4,5-dihydroisoxazole (CAS 19505-59-0), a certified reference material (molecular formula C18H19NO, MW 265.35 g/mol) for analytical method development and quality control.
