Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1,2-Phenylenebis(methylene))bis(triphenylphosphonium) bromide.
(1,2-Phenylenebis(methylene))bis(triphenylphosphonium) bromide (CAS 1519-46-6), molecular formula C44H38P2Br and molecular weight 708.64 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1,2-Phenylenebis(methylene))bis(triphenylphosphonium) bromide (C44H38P2Br) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
