Chemical Structure
Description
Owing to deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, 5α-ANDROSTAN-17αMETHYL-17βOL-[3, 2-c]PYRAZOLE is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 331.51 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).
