Chemical Structure
Description
N-(2-oxo-2-((2-(pyridin-2-yl)ethyl)amino)ethyl)-N-phenylglycine (CAS 1142204-79-2), molecular formula C17H19N3O3 and molecular weight 313.35 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(2-oxo-2-((2-(pyridin-2-yl)ethyl)amino)ethyl)-N-phenylglycine (C17H19N3O3) 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 the protonation state of its nitrogen-containing groups, 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.
