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(1-methyl-1H-pyrazol-5-yl)borate.
Potassium trifluoro(1-methyl-1H-pyrazol-5-yl)borate (CAS 1258323-45-3) is a high-purity analytical reference standard with the molecular formula C4H5BF3N2K and a molecular weight of 188.00 g/mol.
Potassium trifluoro(1-methyl-1H-pyrazol-5-yl)borate (C4H5BF3N2K) contains a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point; 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.
