Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Potassium trifluoro(2-methyl-3,5-dinitrophenyl)borate.
Potassium trifluoro(2-methyl-3,5-dinitrophenyl)borate (CAS 850623-72-2), molecular formula C7H5BF3N2O4K and molecular weight 288.03 g/mol, is a CATO reference standard with documented purity and traceability.
Potassium trifluoro(2-methyl-3,5-dinitrophenyl)borate (C7H5BF3N2O4K) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
