Hydrazoic acid is a chemical compound with the formula HN₃. It is a colorless, volatile liquid that is highly toxic and explosive. This acid is known for its use in organic synthesis and as a precursor to various nitrogen-containing compounds. Due to its instability, it must be handled with extreme caution in controlled environments. The compound is classified as a weak acid and is primarily used in laboratory settings. Its structure consists of a nitrogen atom bonded to a hydrogen atom and two additional nitrogen atoms, forming a linear arrangement. Despite its hazardous nature, hydrazoic acid plays a role in research and industrial applications.
