1-Ethyl-2-nonylquinolin-4(1H)-one CAS 61926-23-6

Description

The occurrence of 1-Ethyl-2-nonylquinolin-4(1H)-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Ethyl-2-nonylquinolin-4(1H)-one (CAS 61926-23-6), molecular formula C20H29NO and molecular weight 299.45 g/mol, is a CATO reference standard with documented purity and traceability.

1-Ethyl-2-nonylquinolin-4(1H)-one (C20H29NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
