Chemical Structure
Description
The occurrence of Methyl 6-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-2-{[(4-chlorophenyl)carbamoyl]amino}-4H,5H,6H,7H-thieno[2,3-c]pyridine-3-carboxylate is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 6-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-2-{[(4-chlorophenyl)carbamoyl]amino}-4H,5H,6H,7H-thieno[2,3-c]pyridine-3-carboxylate (CAS 321430-32-4) is a high-purity analytical reference standard with the molecular formula C22H17Cl2F3N4O3S and a molecular weight of 545.36 g/mol.
Methyl 6-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-2-{[(4-chlorophenyl)carbamoyl]amino}-4H,5H,6H,7H-thieno[2,3-c]pyridine-3-carboxylate (C22H17Cl2F3N4O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/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.
