Safety Profile
The solid may explodespontaneously or on impact, friction or heating to 60°C.Upon decomposition it emits toxic fumes of NOx andSOx.
Synthesis
1,2,3-Benzothiadiazole-1,1-dioxide is prepared by diazotization of sodium 2-aminobenzenesulfinate, which is obtained in three steps from 2-nitroaniline.
storage
1,2,3-Benzothiadiazole-1,1-dioxide can be isolated as yellow-brown needles, but slowly decomposes even at 0 °C and explodes between 45 and 60 °C. A safer alternative is to use it in solution, in which it decomposes smoothly at 10 °C. Preparation and handling should be carried out with good shielding.
