Chemical Structure

1-(5-phenylpyridin-2-yl)ethan-1-one CAS 866326-59-2 chemical structure

Description

The molecular framework of 1-(5-phenylpyridin-2-yl)ethan-1-one (C13H11NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

1-(5-phenylpyridin-2-yl)ethan-1-one (CAS 866326-59-2) is a high-purity analytical reference standard with the molecular formula C13H11NO and a molecular weight of 197.23 g/mol.

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.
