Methyl 4-chloro-3,3-difluorobutanoate (CAS 1447671-69-3) is a high-purity analytical reference standard with the molecular formula C5H7ClF2O2 and a molecular weight of 172.56 g/mol.
Methyl 4-chloro-3,3-difluorobutanoate (C5H7ClF2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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.
