Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1-Benzyl-3-butyl-1H-imidazol-3-ium tetrafluoroborate (CAS 642443-67-2), a certified reference material (molecular formula C14H19N2BF4, MW 302.12 g/mol) for analytical method development and quality control.
The molecular framework of 1-Benzyl-3-butyl-1H-imidazol-3-ium tetrafluoroborate (C14H19N2BF4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
