Chemical Structure
Description
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.
(Fluoromethyl)triphenylphosphonium Tetrafluoroborate (CAS 96385-23-8) is a high-purity analytical reference standard with the molecular formula C19H17FPBF4 and a molecular weight of 382.12 g/mol.
Structurally, (Fluoromethyl)triphenylphosphonium Tetrafluoroborate (C19H17FPBF4) contains organophosphorus functionality, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 382.12 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
