o-Anisidine is a yellow liquid with melting point -1 to 5 °C and density 1.09 g/cm³. The vapor pressure is 0.05 mbar at 20 °C but increases greatly with temperature. It has an aromatic smell and is well absorbed by inhalation, oral ingestion and skin contact. 2-Anisidine is a very toxic agent that causes blood, enzyme and nerve damage with cyanosis and the danger of suffocation. The agent is an experimental carcinogen and is strongly suspected to be also a human carcinogen. 2-Anisidine has dangerous pollutant properties for water.
