Dichlorophenol

Dichlorophenols (DCPs) are any of several chemical compounds which are derivatives of phenol containing two chlorine atoms. There are six isomers:
 * 2,3-Dichlorophenol
 * 2,4-Dichlorophenol
 * 2,5-Dichlorophenol
 * 2,6-Dichlorophenol
 * 3,4-Dichlorophenol
 * 3,5-Dichlorophenol

Dichlorophenols are used as intermediates in the manufacture of more complex chemical compounds, including the common herbicide 2,4-dichlorophenoxyacetic acid (2,4-D).
