Chemical Structure
Description
The occurrence of Potassium (5-chloropyrimidin-2-yl)trifluoroborate is closely related to a salt form, a nitrile group, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Potassium (5-chloropyrimidin-2-yl)trifluoroborate (CAS 1245906-58-4) is a high-purity analytical reference standard with the molecular formula C4H2BClF3N2K and a molecular weight of 220.43 g/mol.
The molecular framework of Potassium (5-chloropyrimidin-2-yl)trifluoroborate (C4H2BClF3N2K) is characterized by a salt form, a nitrile group, 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. 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.
