Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block in the formation of nitrogen-containing heterocycles, such as imidazoles and pyridines, which are common structures in bioactive molecules. As a Schiff base, it has applications in coordination chemistry and as ligands in catalytic reactions. Its reactivity toward nucleophiles and ability to undergo condensation make it valuable in the development of dyes, sensors, and functional materials.
