Used primarily as an intermediate in organic synthesis, especially in the preparation of heterocyclic compounds. It plays a key role in the development of pharmaceuticals, including antimicrobial and antifungal agents, due to its ability to form hydrazone derivatives with bioactive properties. Also employed in the synthesis of dyes and agrochemicals, where nitro and chloro functional groups contribute to reactivity and molecular diversity. Its hydrazide group allows for easy modification, making it valuable in medicinal chemistry research for building more complex molecules.
