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,[3] defoliant, and glue preservative.[4] It is a clear to yellowish crystalline solid with a strong, phenolic odor. It decomposes on heating to produce toxic and corrosive fumes including hydrogen chloride and chlorine.

Preparation

2,4,6-Trichlorophenol is produced industrially by the electrophilic chlorination of phenol:[5]

Health effects

In animal models, consumption of 2,4,6-trichlorophenol leads to an increased incidence of

polychlorinated dibenzofurans (PCDFs), and other contaminants.[8]

Environmental effects

2,4,6-Trichlorophenol is an environmental pollutant that has been found in fresh water lakes such as the Great Lakes.[9]
