Release Time: 2022-11-24

Brief introduction

Ortho Anisidine is a yellow liquid with a melting point of -1 to 5 °C and a density of 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. Ortho 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 a human carcinogen also.
