Tetrazene (1-(5-tetrazolyl)-4-guanyl tetrazene hydrate) is an explosive material used for sensitization of the priming compositions. It is a derivative of the compound with the IUPAC name tetrazene.

Tetrazene is slightly more impact-sensitive than mercury fulminate. When pressed enough, its sensitivity is reduced or destroyed; it also decomposes in boiling water. In contact with fire, it readily explodes, producing large amount of black smoke. It is prepared by reacting sodium nitrite with an aminoguanidine salt dissolved in acetic acid at 30–40 °C.
