Used in pharmaceutical research as a key intermediate for synthesizing various biologically active compounds. It plays a role in the development of potential drug candidates, particularly in the creation of molecules targeting neurological and psychiatric disorders. Its hydrazine moiety allows it to participate in condensation reactions, forming heterocyclic structures that are often found in medicinal chemistry. Additionally, it is utilized in organic synthesis to produce dyes and agrochemicals due to its ability to form stable intermediates. Its halogenated aromatic structure contributes to its reactivity in cross-coupling reactions, making it valuable in the preparation of complex organic molecules.
