Chemical Structure
Description
The occurrence of 4-Bromo-N-{3-[5-(trifluoromethyl)pyridin-2-yl]phenyl}benzene-1-sulfonamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromo-N-{3-[5-(trifluoromethyl)pyridin-2-yl]phenyl}benzene-1-sulfonamide (CAS 1092346-17-2) is a high-purity analytical reference standard with the molecular formula C18H12BrF3N2O2S and a molecular weight of 457.26 g/mol.
4-Bromo-N-{3-[5-(trifluoromethyl)pyridin-2-yl]phenyl}benzene-1-sulfonamide (C18H12BrF3N2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
