Triphenyl(3-pyridylmethyl)phosphonium chloride CAS 79296-92-7

Description

The occurrence of Triphenyl(3-pyridylmethyl)phosphonium chloride is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Triphenyl(3-pyridylmethyl)phosphonium chloride (CAS 79296-92-7) is a high-purity analytical reference standard with the molecular formula C24H21NPCl and a molecular weight of 389.86 g/mol.

Triphenyl(3-pyridylmethyl)phosphonium chloride (C24H21NPCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
