Chemical Structure
Description
The molecular framework of 4-[N-(2-Pyridylamino)ethoxy]benzaldehyde (C14H14N2O2) 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).
4-[N-(2-Pyridylamino)ethoxy]benzaldehyde (CAS 643764-87-8), molecular formula C14H14N2O2 and molecular weight 242.27 g/mol, is a CATO reference standard with documented purity and traceability.
