Methyl 2,2-Difluoro-1,3-benzodioxole-5-carboxylate (CAS 773873-95-3) is a high-purity analytical reference standard with the molecular formula C9H6F2O4 and a molecular weight of 216.14 g/mol.
Methyl 2,2-Difluoro-1,3-benzodioxole-5-carboxylate (C9H6F2O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
