Chemical Structure
Description
The occurrence of Potassium (cyanomethyl)trifluoroborate is closely related to fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Potassium (cyanomethyl)trifluoroborate (CAS 888711-58-8), a certified reference material (molecular formula C2H2BF3NK, MW 146.95 g/mol) for analytical method development and quality control.
Owing to fluorine substitution, Potassium (cyanomethyl)trifluoroborate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.95 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
