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.[1]
The molecule is planar.[2] The hydrogen bonding pattern in the hydrate supports the assignment of NH being adjacent to carbon in the ring.[3]
