Bis(4-trifluoromethylphenyl)phosphine CAS 99665-68-6

Description

The occurrence of Bis(4-trifluoromethylphenyl)phosphine is closely related to organophosphorus functionality, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Bis(4-trifluoromethylphenyl)phosphine (CAS 99665-68-6), a certified reference material (molecular formula C14H9F6P, MW 322.19 g/mol) for analytical method development and quality control.

Owing to organophosphorus functionality, fluorine substitution, a polycyclic aromatic system, Bis(4-trifluoromethylphenyl)phosphine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
