Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of certain antidepressants and antitubercular agents. It serves as a building block in organic synthesis due to its reactive hydrazine functionality, enabling the formation of hydrazone and heterocyclic compounds. Also employed in the development of agrochemicals and specialty polymers where controlled nitrogen release or curing properties are required. Its hydrochloride salt form enhances stability and handling safety in industrial processes.
