Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block for nitrogen-containing heterocyclic compounds due to the reactivity of both the pyridine ring and the ethylaminomethyl side chain. Commonly employed in the development of catalysts and ligands for metal-catalyzed reactions. Also finds use in the synthesis of functional materials and specialty polymers where amine and pyridine functionalities enhance solubility or coordination properties.
