Description

Compared with other compounds in its class, the molecular weight of 692.24 g/mol gives ((2,5-Dimethyl-1,4-phenylene)bis(methylene))bis(triphenylphosphonium) chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies ((2,5-Dimethyl-1,4-phenylene)bis(methylene))bis(triphenylphosphonium) chloride (CAS 1519-48-8), a certified reference material (molecular formula C46H42P2Cl, MW 692.24 g/mol) for analytical method development and quality control.

Based on its molecular formula C46H42P2Cl, ((2,5-Dimethyl-1,4-phenylene)bis(methylene))bis(triphenylphosphonium) chloride contains organophosphorus functionality, chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 692.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
