Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (3S)-7-Chloro-1-(5-chloro-4-methoxy-2-nitrophenyl)-6-fluoro-3-methyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 424.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
