Chemical Structure
Description
The molecular framework of (2,3,4,5,6-Pentafluorophenyl)methyl-triphenyl-phosphonium;bromide (C25H17F5PBr) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies (2,3,4,5,6-Pentafluorophenyl)methyl-triphenyl-phosphonium;bromide (CAS 13509-91-6), a certified reference material (molecular formula C25H17F5PBr, MW 523.28 g/mol) for analytical method development and quality control.
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.
As a certified reference material (CRM), (2,3,4,5,6-Pentafluorophenyl)methyl-triphenyl-phosphonium;bromide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
