Chemical Structure
Description
2-(Difluoromethyl)-3-iodo-4-methoxypyridine-5-sulfonamide (CAS 1806948-50-4) is a high-purity analytical reference standard with the molecular formula C7H7F2IN2O3S and a molecular weight of 364.11 g/mol.
2-(Difluoromethyl)-3-iodo-4-methoxypyridine-5-sulfonamide (C7H7F2IN2O3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
