Azides are chemical compounds that contain the azide group, which is represented by the formula N₃ (three nitrogen atoms connected in a linear arrangement). They are often used in organic synthesis and can be found in various applications, including pharmaceuticals and materials science. Azides are known for their reactivity, particularly in the presence of heat or shock, which can lead to explosive decomposition. In addition to their synthetic uses, azides can also serve as precursors for nitrogen-containing compounds and are utilized in click chemistry, a method for rapidly assembling complex molecules. Their unique properties make them valuable in research and industrial applications, although safety precautions are essential due to their potential hazards.
