Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, tert-Butyl (S)-2-(4-isopropylphenyl)piperazine-1-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.43 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).
