Chemical Structure
Description
Owing to deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 8-Chloro-3-methoxy-11-(1-methyl-4-piperidinyl)-6,11-dihydro-5H-benzo[5,6]-cyclohepta[1,2-b]pyridin-11-ol D4 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 376.91 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.
