Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of indazole-based drugs. Its structure allows for cyclization reactions that are essential in forming heterocyclic frameworks common in bioactive molecules. It is also employed in the preparation of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Due to the hydrazine functionality, it participates in condensation reactions to form hydrazones, which are useful in medicinal chemistry and drug design. Its brominated aromatic ring enables further functionalization via cross-coupling reactions, making it valuable in multi-step organic syntheses for generating compound libraries in drug discovery.
