Application

2,4-Dichlorophenol was used to study the degradative pathway of 2,4-dichlorophenol by Phanerochaete chrysosporium. It was used to study the competitive sorption of anthropogenic organic compounds in soils.

General description

2,4-Dichlorophenol is anthropogenic organic compound and a common water and soil pollutant. It is precursor required for the synthesis of herbicides:2,4-dichloro- and 2,4,5-trichloro-phenoxyacetic acids and wood preservative: pentachlorophenol.
