HYDRAZINE HYDROCHLORIDE

Hydrazine Hydrochloride (N2H4·HCl) is an important chemical compound that plays a significant role in various industries due to its reactivity and versatility. It is a colorless, corrosive liquid with a distinct ammonia-like odor, widely used in chemical synthesis, pharmaceutical applications, water treatment, and fuel cells. Hydrazine Hydrochloride is primarily the hydrochloride salt of hydrazine (N2H4), a compound that is itself well-known for its use as a reducing agent and a key building block in the production of various chemicals.

While hydrazine itself is highly reactive and toxic, Hydrazine Hydrochloride is more stable and easier to handle, making it suitable for various applications. The compound is used in industrial manufacturing, pharmaceuticals, agriculture, and energy generation systems.
