2-Ethoxy-N-(pyridin-4-ylmethyl)aniline CAS 1019573-74-0

Description

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.

2-Ethoxy-N-(pyridin-4-ylmethyl)aniline (CAS 1019573-74-0), molecular formula C14H16N2O and molecular weight 228.29 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Ethoxy-N-(pyridin-4-ylmethyl)aniline (C14H16N2O) 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 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).

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.
