Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, (2R,3S)-1'-benzyl-2-phenyl-2-(trifluoromethyl)-2H-spiro[furan-3,3'-indoline]-2',5(4H)-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 437.41 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).
