CATO supplies Potassium (E)-3-bromo-1,4-dichlorobut-2-en-2-yltrifluoroborate (CAS 1692895-64-9), a certified reference material (molecular formula C4H4BBrCl2F3K, MW 309.78 g/mol) for analytical method development and quality control.
Potassium (E)-3-bromo-1,4-dichlorobut-2-en-2-yltrifluoroborate (C4H4BBrCl2F3K) contains a salt form, fluorine/chlorine/bromine 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.
