Chemical Structure
Description
Structurally, 1-(4-Bromophenyl)-2-({1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1H-imidazol-2-yl}sulfanyl)ethan-1-one (C17H10BrClF3N3OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 476.70 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
