Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, Benzo[1,2-b:3,4-b']bisbenzofuran is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 258.27 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).
