Chemical Structure
Description
(1,4-Phenylenebis(methylene))bis(triphenylphosphonium) chloride (CAS 1519-47-7), molecular formula C44H38P2Cl and molecular weight 664.19 g/mol, is a CATO reference standard with documented purity and traceability.
(1,4-Phenylenebis(methylene))bis(triphenylphosphonium) chloride (C44H38P2Cl) contains organophosphorus functionality, chlorine 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 (1,4-Phenylenebis(methylene))bis(triphenylphosphonium) chloride 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.
