Chemical Structure
Description
Owing to a steroid core, sulfur-containing functionality, a hydroxyl group, an ether linkage, 2,5-Dimethyl-3-(2-thiomethylphenyl)propiophenone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.42 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).
