Chemical Structure

4-(1,1-Diphenylethyl)pyridine CAS 109975-61-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 259.34 g/mol gives 4-(1,1-Diphenylethyl)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-(1,1-Diphenylethyl)pyridine (CAS 109975-61-3), a certified reference material (molecular formula C19H17N, MW 259.34 g/mol) for analytical method development and quality control.

The molecular framework of 4-(1,1-Diphenylethyl)pyridine (C19H17N) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
