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] 5-Aminotetrazole has found applications in heterocyclic chemistry, particularly as a synthon for numerous multicomponent reactions.[4] References1. ^Lesnikovich, A.
