(4-Cyanobenzyl)triphenylphosphonium chloride CAS 20430-33-5

Description

Compared with other compounds in its class, the molecular weight of 413.88 g/mol gives (4-Cyanobenzyl)triphenylphosphonium chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(4-Cyanobenzyl)triphenylphosphonium chloride (CAS 20430-33-5) is a high-purity analytical reference standard with the molecular formula C26H21NPCl and a molecular weight of 413.88 g/mol.

The molecular framework of (4-Cyanobenzyl)triphenylphosphonium chloride (C26H21NPCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
