Chemical Structure
Description
The molecular framework of N-fluoro-3,5-dichloropyridiniumtetrafluoroborate (C5H3Cl2FNBF4) is characterized by fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies N-fluoro-3,5-dichloropyridiniumtetrafluoroborate (CAS 109705-15-9), a certified reference material (molecular formula C5H3Cl2FNBF4, MW 253.79 g/mol) for analytical method development and quality control.
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.
