Chemical Structure
Description
AZM 475271 (C23H27ClN4O3) contains a steroid core, an amide 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.
AZM 475271 (CAS 476159-98-5), molecular formula C23H27ClN4O3 and molecular weight 442.94 g/mol, is a CATO reference standard with documented purity and traceability.
