Chemical Structure
Description
The molecular framework of 3-(1-Ethyl-5,6-dimethyl-1H-1,3-benzodiazol-2-yl)-1,2-dihydropyridin-2-one (C16H17N3O) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
3-(1-Ethyl-5,6-dimethyl-1H-1,3-benzodiazol-2-yl)-1,2-dihydropyridin-2-one (CAS 923249-05-2) is a high-purity analytical reference standard with the molecular formula C16H17N3O and a molecular weight of 267.33 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.
