Chemical Structure
Description
The occurrence of Pentane-1,5-diylbis(triphenylphosphonium) bromide is closely related to organophosphorus functionality, bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Pentane-1,5-diylbis(triphenylphosphonium) bromide (CAS 22884-31-7) is a high-purity analytical reference standard with the molecular formula C41H40P2Br and a molecular weight of 674.62 g/mol.
The molecular framework of Pentane-1,5-diylbis(triphenylphosphonium) bromide (C41H40P2Br) is characterized by organophosphorus functionality, 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. 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 Pentane-1,5-diylbis(triphenylphosphonium) bromide 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.
