Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Potassium trifluoro(hex-1-yn-1-yl)borate (CAS 244301-59-5) is a high-purity analytical reference standard with the molecular formula C6H9BF3K and a molecular weight of 188.04 g/mol.
Potassium trifluoro(hex-1-yn-1-yl)borate (C6H9BF3K) contains 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.
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.
