Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of certain antipsychotic and antihypertensive drugs. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building complex heterocyclic systems. Also employed in the development of agrochemicals, including herbicides and plant growth regulators, due to its reactivity and stability. Additionally, it serves as a building block in the preparation of specialty polymers and functional materials where nitrogen-containing aromatic frameworks are required.
