The exclusive Actual physical Qualities of NO2 fuel permit for sterilant dispersion in an enclosed ecosystem at area temperature and atmospheric force. The mechanism for lethality may be the degradation of DNA while in the spore core by way of nitration with the phosphate backbone, which kills the exposed organism because it absorbs NO2. This degradations occurs at even really minimal concentrations in the gas.[36] NO2 has a boiling place of 21 °C (70 °File) at sea degree, which results in a comparatively really saturated vapour force at ambient temperature.
