CATO supplies (E)-4,5,5,5-tetrafluoro-4-(trifluoromethyl)pent-2-enoic Acid (CAS 243139-64-2), a certified reference material (molecular formula C6H3F7O2, MW 240.08 g/mol) for analytical method development and quality control.
(E)-4,5,5,5-tetrafluoro-4-(trifluoromethyl)pent-2-enoic Acid (C6H3F7O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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.
