Chemical Structure
Description
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.
(4-Cyanobenzyl)triphenylphosphonium bromide (CAS 26104-68-7) is a high-purity analytical reference standard with the molecular formula C26H21NPBr and a molecular weight of 458.34 g/mol.
Based on its molecular formula C26H21NPBr, (4-Cyanobenzyl)triphenylphosphonium bromide contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 458.34 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.
