3-Chloro-2,2,3,3-tetrafluoropropionic Acid (CAS 661-82-5), molecular formula C3HClF4O2 and molecular weight 180.49 g/mol, is a CATO reference standard with documented purity and traceability.
3-Chloro-2,2,3,3-tetrafluoropropionic Acid (C3HClF4O2) 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.
