Chemical Structure
Description
The occurrence of Triphenyl-[[4-[4-(triphenylphosphaniumylmethyl)phenyl]phenyl]methyl]phosphonium dichloride is closely related to organophosphorus functionality, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Triphenyl-[[4-[4-(triphenylphosphaniumylmethyl)phenyl]phenyl]methyl]phosphonium dichloride (CAS 54050-02-1), molecular formula C50H42P2Cl and molecular weight 740.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Triphenyl-[[4-[4-(triphenylphosphaniumylmethyl)phenyl]phenyl]methyl]phosphonium dichloride (C50H42P2Cl) is characterized by organophosphorus functionality, chlorine 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. 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.
CATO manufactures Triphenyl-[[4-[4-(triphenylphosphaniumylmethyl)phenyl]phenyl]methyl]phosphonium dichloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
