Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for central nervous system (CNS) drugs. It serves as a building block in heterocyclic chemistry due to its fused imidazole structure, which is valuable in creating compounds with biological activity. Also employed in research settings for the design of novel medicinal agents, especially those targeting neurological and psychiatric disorders. Its hydrochloride salt form enhances solubility and stability, making it suitable for use in aqueous reaction systems and purification processes.
