2,3,4,5,6-Pentachloro-1-fluoropyridin-1-ium tetrafluoroborate CAS 132041-54-4

Description

The occurrence of 2,3,4,5,6-Pentachloro-1-fluoropyridin-1-ium tetrafluoroborate is closely related to fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,3,4,5,6-Pentachloro-1-fluoropyridin-1-ium tetrafluoroborate (CAS 132041-54-4), a certified reference material (molecular formula C5Cl5FNBF4, MW 357.11 g/mol) for analytical method development and quality control.

Structurally, 2,3,4,5,6-Pentachloro-1-fluoropyridin-1-ium tetrafluoroborate (C5Cl5FNBF4) contains fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.5, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 357.11 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
