Chemical Structure
Description
6-(5-Chloro-1-(4-methoxyphenyl)-6-oxo-1,6-dihydropyridazin-4-yl)-2-(1H-pyrrol-1-yl)-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carbonitrile (C23H18ClN5O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
