Hydrazine derivatives are chemical compounds that are derived from hydrazine, a simple nitrogen-based molecule. These derivatives often contain additional functional groups, which can modify their properties and reactivity. They are used in various applications, including as rocket propellants, in pharmaceuticals, and as intermediates in organic synthesis. Many hydrazine derivatives exhibit unique characteristics, such as high reactivity and the ability to form stable complexes with metals. Their versatility makes them valuable in research and industry, particularly in the development of new materials and chemical processes.
