1. Long-term storage in the air is easy to oxidize and the color becomes darker, with sublimation. It has a faint peculiar smell and is irritating to the skin. It is combustible in case of open flame and high heat.

2. Toxic, especially incompletely refined products mixed with diphenylamine, will be toxic if ingested or inhaled. This product can be absorbed by the skin, causing skin allergies, dermatitis, discoloration of hair and nails, inflammation of the conjunctiva and cornea, irritation of the stomach and intestines, damage to the kidneys and liver, and cause hemolytic anemia, abdominal pain, and tachycardia.
