Cyanogen azide, N3CN or CN4, is an azide compound of carbon and nitrogen which is an oily, colourless liquid at room temperature.[1] It is a highly explosive chemical that is soluble in most organic solvents, and normally handled in dilute solution in this form.[1][2][3] It was first synthesised by F. D. Marsh at DuPont in the early 1960s.[1][4] There had been earlier claims of discovering it as a crystalline solid, which were incorrect.[5]

Cyanogen azide is a primary explosive, although it is far too unstable for practical use as an explosive and is extremely dangerous outside dilute solution.[6][7] Its use in chemistry has been as a reagent prepared in situ for use in the synthesis of chemicals such as diaminotetrazoles, either in dilute solution or as a gas at reduced pressure.[8][9][10][5][11][12][13] It can be synthesised at below room temperature from the reaction of sodium azide with either cyanogen chloride[1] or cyanogen bromide,[4] dissolved in a solvent such as acetonitrile; this reaction must be done with care due to the production of shock-sensitive byproducts from trace moisture.[4][11]
