1,1′-Azobis-1,2,3-triazole is a moderately explosive but comparatively stable chemical compound which contains a long continuous chain of nitrogen atoms, with an unbroken chain of eight nitrogen atoms cyclised into two 1,2,3-triazole rings. It is stable up to 194 °C. The compound exhibits cis–trans isomerism at the central azo group: the trans isomer is more stable and is yellow, while the cis isomer is less stable and is blue. The two rings are aromatic and form a conjugated system with the azo linkage. This chromophore allows the trans compound to be isomerised to the cis when treated with an appropriate wavelength of ultraviolet light.
