2-Naphthol

CAS: 135-19-3

2-Naphthol is an organic compound with the chemical formula C10H7O. It is a derivative of naphthalene, and is produced by the condensation of two molecules of malonic acid in the presence of a reducing agent such as sodium borohydride. 2-Naphthol is used as a pesticide and as a chemical intermediate in the production of other chemicals. 2-Naphthol has been shown to be toxic to humans and animals; it may cause liver damage, kidney damage, and skin irritation. The acute oral LD50 for rats is 690 mg/kg body weight. 2-Naphthol binds to cell receptors that are involved in a variety of physiological processes including heme transport, phagocytosis, oxidative burst, chemotaxis, and respiratory burst. This binding inhibits these functions leading to cell death.
