Chemical Structure
Description
CATO supplies Triphenyl(3,3,3-trifluoropropyl)phosphonium iodide (CAS 128622-15-1), a certified reference material (molecular formula C21H19F3PI, MW 486.25 g/mol) for analytical method development and quality control.
Based on its molecular formula C21H19F3PI, Triphenyl(3,3,3-trifluoropropyl)phosphonium iodide contains organophosphorus functionality, fluorine/iodine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 486.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
