2,4,6-Trichlorophenol, also known as TCP, phenaclor, Dowicide 2S, Dowcide 2S, omal, is a chlorinated phenol that has been used as a fungicide, herbicide, insecticide, antiseptic,[1] defoliant, and glue preservative.[2] It is a yellow solid with a strong, sweet odour. It decomposes on heating to produce toxic and corrosive fumes including hydrogen chloride and chlorine.

Health effects[edit]

2,4,6-Trichlorophenol is carcinogenic in animals, causing lymphomas, leukemia, and liver cancer via oral exposure.[3][4] It is classified as Group B2 (probable human carcinogen) by the United States Environmental Protection Agency.[4] The technical grade of this substance may contain polychlorinated dibenzodioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and other contaminants.[5]

Environmental effects[edit]

2,4,6-Trichlorophenol is an environmental pollutant that has been found in fresh water lakes such as the Great Lakes.[6]
