Description of key information

Based upon the vapour pressure of 5-nitro-o-anisidine from variuos sources it was found to be in the range of 0.00013 - 0.0000401 mm Hg at 25 °C. For the purpose of chemical safty assessment the higher value is taken as 0.00013 based upon the weight of evidence approch. This value after conversion equivalent to 0.0399 Pa at 25 °C.
