Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It serves as a building block in the preparation of heterocyclic compounds, particularly in the formation of indoles and other nitrogen-containing rings through cyclization reactions. Its hydrazine functionality allows it to participate in condensation reactions, making it valuable in the development of dyes, pigments, and functional materials. Commonly employed in research settings for the design of novel bioactive molecules, including potential antitumor and antimicrobial agents.
