Chemical Structure
Description
N-((1-ethyl-2-oxo-1,2,3,4-tetrahydroquinoline-3-carbonyl)oxy)acetamide (CAS 2306278-60-2), molecular formula C14H16N2O4 and molecular weight 276.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-((1-ethyl-2-oxo-1,2,3,4-tetrahydroquinoline-3-carbonyl)oxy)acetamide (C14H16N2O4) 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 the protonation state of its nitrogen-containing groups, 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.
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.
