Chemical Structure
Description
1,3-Dimethyl 2-(2,3-difluoro-6-nitrophenyl)propanedioate (C11H9F2NO6) contains a nitrogen-containing heterocyclic scaffold, an amide 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1,3-Dimethyl 2-(2,3-difluoro-6-nitrophenyl)propanedioate (CAS 1400644-66-7), molecular formula C11H9F2NO6 and molecular weight 289.19 g/mol, is a CATO reference standard with documented purity and traceability.
