(1S,2R)-2-fluoro-1-methylcyclopropane-1-carboxylic acid (CAS 128230-88-6), molecular formula C5H7FO2 and molecular weight 118.11 g/mol, is a CATO reference standard with documented purity and traceability.
(1S,2R)-2-fluoro-1-methylcyclopropane-1-carboxylic acid (C5H7FO2) 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.
