Chemical properties: m-toluidine gradually turns brown when exposed to light or oxidized in air. Generate salts with acid. Other properties are the same as aniline.
Storage precautions: Store in a cool and ventilated warehouse. Stay away from sources of fire and heat. The packaging requires sealing and must not come into contact with air. It should be stored separately from oxidants, acids, and edible chemicals, and avoid mixing storage. Equip with corresponding types and quantities of fire-fighting equipment. The storage area should be equipped with emergency response equipment for leaks and suitable containment materials.
