Chemical Structure

Pentadecyltriphenylphosphonium Bromide CAS 1944-80-5 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.

Pentadecyltriphenylphosphonium Bromide (CAS 1944-80-5) is a high-purity analytical reference standard with the molecular formula C33H64PBr and a molecular weight of 571.75 g/mol.

The molecular framework of Pentadecyltriphenylphosphonium Bromide (C33H64PBr) is characterized by organophosphorus functionality, bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
