Chemical Structure
Description
The molecular framework of 1-Benzyl-6-oxo-1,6-dihydropyridine-3-carboxylic Acid (C13H11NO3) 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-Benzyl-6-oxo-1,6-dihydropyridine-3-carboxylic Acid (CAS 4332-79-0) is a high-purity analytical reference standard with the molecular formula C13H11NO3 and a molecular weight of 229.23 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.
