Chemical Structure
Description
1,4-dimethyl 2-(difluoromethoxy)butanedioate (C7H10F2O5) contains a carboxylic acid 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.
1,4-dimethyl 2-(difluoromethoxy)butanedioate (CAS 1803598-58-4) is a high-purity analytical reference standard with the molecular formula C7H10F2O5 and a molecular weight of 212.15 g/mol.
