Chemical Structure
Description
1-(2-Methoxy-2-oxoethyl)pyridazin-1-ium bromide (C7H9N2O2Br) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine 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).
1-(2-Methoxy-2-oxoethyl)pyridazin-1-ium bromide (CAS 7593-56-8) is a high-purity analytical reference standard with the molecular formula C7H9N2O2Br and a molecular weight of 233.06 g/mol.
