Used as an intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds. It plays a key role in the development of pharmaceuticals due to its ability to form hydrazone derivatives, which are important in drug design. Commonly employed in the synthesis of anticonvulsant and anti-inflammatory agents. Also utilized in the production of dyes and functional materials where hydrazine-containing building blocks are required. Its reactivity with carbonyl compounds makes it valuable in condensation reactions for creating nitrogen-rich structures.
