Description
CATO manufactures (1,3-Phenylenebis(methylene))bis(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.
(1,3-Phenylenebis(methylene))bis(triphenylphosphonium) bromide (CAS 10273-74-2) is a high-purity analytical reference standard with the molecular formula C44H38P2 and a molecular weight of 628.72 g/mol.
The molecular framework of (1,3-Phenylenebis(methylene))bis(triphenylphosphonium) bromide (C44H38P2) is characterized by organophosphorus functionality, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
