Compared with other compounds in its class, the molecular weight of 383.27 g/mol gives Triphenyl(prop-1-en-1-yl)phosphonium bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Triphenyl(prop-1-en-1-yl)phosphonium bromide (CAS 7301-94-2), a certified reference material (molecular formula C21H20PBr, MW 383.27 g/mol) for analytical method development and quality control.
Triphenyl(prop-1-en-1-yl)phosphonium bromide (C21H20PBr) contains organophosphorus functionality, bromine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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(prop-1-en-1-yl)phosphonium 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.
