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.
Triphenyl[4-(trifluoromethyl)benzyl]phosphonium Bromide (CAS 38733-98-1) is a high-purity analytical reference standard with the molecular formula C26H21F3PBr and a molecular weight of 501.33 g/mol.
The molecular framework of Triphenyl[4-(trifluoromethyl)benzyl]phosphonium Bromide (C26H21F3PBr) is characterized by organophosphorus functionality, fluorine/bromine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
