Description of key information

The boiling point of 5-nitro-o-anisidine by the distillation method was found to be 315 °C at the atmospheric pressure of 955 hPa. No decomposition of 5-nitro-o-anisidine was observed at the boiling point. This boiling point value at 101325 Pa is equivalent to 334.21°C.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
334.21 °C

Additional information

The boiling point of 5-nitro-o-anisidine by the distillation method was found to be 315 °C at the atmospheric pressure of 955 hPa. No decomposition of 5-nitro-o-anisidine was observed at the boiling point.The other authoritative source of information though indicate the boiling point to be in the range of 303°C - 351°C.However for the purpose of the dossier as well as for the chemical safety report, the boiling point of the key study which is 315°C shall be considered. This boiling point value at 101325 Pa is equivalent to 334.21°C.
