Used primarily as an intermediate in organic synthesis, especially in the preparation of heterocyclic compounds such as pyrazoles and indoles. It serves as a building block in pharmaceuticals and agrochemicals due to its reactivity with carbonyl compounds, forming hydrazones that are key in various condensation reactions. Also employed in the development of dyes and functional materials where nitrogen-containing precursors are required. Its ability to act as a ligand in coordination chemistry enables use in metal complex synthesis for catalytic applications.
