| White solid|
5-Aminotetrazole is an organic compound with the formula HN4CNH2. It is a white solid that can be obtained both in anhydrous and hydrated forms. The compound has a particularly high nitrogen content of 80%. Partly for this reason, the compound is prone to decomposition to nitrogen gas (N2). It has been widely investigated for gas-generating systems, such as airbags and blowing agents.
The molecule is planar. The hydrogen bonding pattern in the hydrate supports the assignment of NH being adjacent to carbon in the ring.
