What is 2-chlorophenol?

2-Chlorophenol or ortho-chlorophenol is an organic compound, a derivative of phenol. Related compounds are used as a disinfectant agents and various pesticides. This particular compound has few other applications but is an intermediate in the polychlorination of phenol.2-chlorophenol appears as a colorless to amber liquid with an unpleasant, penetrating odor. Sinks in water and slowly dissolves.


At one time, chlorophenol-treatment was widely used in agriculture, to prevent wood decay in buildings, food containers, and horticultural timbers. Recently, such chlorophenol applications have been considerably restricted in some countries, and as a result, the quantities of non-PCP chlorophenols used in agriculture are minor.
