Triphenyl(phenylethynyl)lead(IV) CAS 5072-98-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Triphenyl(phenylethynyl)lead(IV).

Triphenyl(phenylethynyl)lead(IV) (CAS 5072-98-0) is a high-purity analytical reference standard with the molecular formula C26H20Pb and a molecular weight of 539.64 g/mol.

The molecular framework of Triphenyl(phenylethynyl)lead(IV) (C26H20Pb) is characterized by 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).

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.
