Chemical Structure
Description
The occurrence of Potassium (2,4-Difluorophenyl)trifluoroborate is closely related to fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Potassium (2,4-Difluorophenyl)trifluoroborate (CAS 871231-41-3) is a high-purity analytical reference standard with the molecular formula C6H3BF5K and a molecular weight of 219.99 g/mol.
Structurally, Potassium (2,4-Difluorophenyl)trifluoroborate (C6H3BF5K) contains fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 219.99 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
