Aminobiphenol

Aminobiphenol (C₁₂H₁₁N) is a chemical compound contained in tobacco smoke, with a proven carcinogenic effect.

• Physical condition: crystals between colourless and white, turn dark by exposure to air or light.
• Chemical hazards: the substance breaks down by heating it intensely, producing toxic nitrogen oxides fumes. It reacts violently with oxidants, causing fire and explosion.
• Exposure limits: Unestablished TLV. Unestablished MAK.
• Exposure paths: the substance can be absorbed by inhalation of steam and aerosol and by ingestion.
• Inhalation risks: evaporation at 20 °C is despicable; however, a harmful concentration of particles in the air can be quickly reached.
• Short-term exposure effects: the substance can cause blood effects, leading to the formation of metahemoglobin. Exposure to high concentrations can lead to death. Medical surveillance is recommended.
• Prolonged or repeated exposure effects: prolonged or repeated contact can raise skin awareness. Animal experimentation shows that this substance may cause toxic effects in human reproduction.
