Chemical Structure
Description
The molecular framework of (E)-(3,7-Dimethylocta-2,6-dien-1-yl)triphenylphosphonium bromide (C28H32PBr) 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.
(E)-(3,7-Dimethylocta-2,6-dien-1-yl)triphenylphosphonium bromide (CAS 41273-34-1), molecular formula C28H32PBr and molecular weight 479.44 g/mol, is a CATO reference standard with documented purity and traceability.
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.
