Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-Amino-2,2-difluorocyclopropanecarboxylic acid (CAS 734528-48-4) is a high-purity analytical reference standard with the molecular formula C4H5F2NO2 and a molecular weight of 137.08 g/mol.
1-Amino-2,2-difluorocyclopropanecarboxylic acid (C4H5F2NO2) contains an amide group, 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.
CATO manufactures 1-Amino-2,2-difluorocyclopropanecarboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
