N2H4, commonly known as hydrazine, is a colorless, flammable liquid with a distinct ammonia-like odor. It is primarily used as a rocket propellant and in various industrial applications, including the production of pharmaceuticals and agricultural chemicals. Hydrazine is known for its high energy content, making it effective in propulsion systems. In addition to its use in aerospace, N2H4 serves as a reducing agent in chemical reactions and can be utilized in the synthesis of other compounds. However, it is important to handle hydrazine with care, as it is toxic and can pose health risks if inhaled or ingested.
