Methyl azide is a chemical compound from the group of azides with the empirical formula CH 3 N 3 . It is characterized by a methylation of sodium azide , for example with dimethyl sulfate produced. The first synthesis was described by Otto Dimroth and Gustav Wilhelm Wislicenus in 1905. The compound is relatively stable against heating, so it decomposes only slowly at 200 ° C, but explosively at 500 ° C. The decomposition takes place in a first order reaction, whereby nitrogen and methyl nitrene are formed as primary products:
