Chemical Structure
Description
Sembragiline (C19H19FN2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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.
Sembragiline (CAS 676479-06-4), molecular formula C19H19FN2O3 and molecular weight 342.36 g/mol, is a CATO reference standard with documented purity and traceability.
