Use

Although the toxicity of 2-naphthol is of low order in test animals, ingestion of large amounts may result in nausea, vomiting, diarrhea, abdominal pain, convulsions, and hemolytic anemia. Death may result from respiratory failure. The oral LD50 value in rats is in the range 2000 mg/kg. 2-Naphthol is slightly more toxic than 1-naphthol [9015-3], the oral LD50 value of which is in the range 2500 mg/kg.Skin contact can produce peeling of the skin and pigmentation.
