[2-Oxo-2-(4-pyridyl)ethyl]-triphenyl-phosphonium;bromide CAS 1462249-70-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including [2-Oxo-2-(4-pyridyl)ethyl]-triphenyl-phosphonium;bromide.

CATO supplies [2-Oxo-2-(4-pyridyl)ethyl]-triphenyl-phosphonium;bromide (CAS 1462249-70-2), a certified reference material (molecular formula C25H21NOPBr, MW 462.33 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution, [2-Oxo-2-(4-pyridyl)ethyl]-triphenyl-phosphonium;bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 462.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
