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.
1-Benzyl-4-hydroxy-3,6-diphenylpyridin-2(1H)-one (CAS 119022-25-2) is a high-purity analytical reference standard with the molecular formula C24H19NO2 and a molecular weight of 353.41 g/mol.
The molecular framework of 1-Benzyl-4-hydroxy-3,6-diphenylpyridin-2(1H)-one (C24H19NO2) is characterized by a steroid core, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
