Used as a reducing agent in organic synthesis, particularly in the preparation of hydrazones and amines. Employed in the pharmaceutical industry for the production of certain drugs, including antitubercular agents and agrochemicals. Serves as an intermediate in the synthesis of dyes, pigments, and photographic chemicals. Applied in electroless plating processes to reduce metal ions to their metallic form, especially in nickel and copper plating. Also utilized in the development of blowing agents for polymer foams, where it decomposes to release nitrogen gas. Its stability compared to free hydrazine makes it preferred in formulations requiring controlled reactivity and safer handling.
