Application

3,4-Dichlorophenol (3,4-DCP) is used in the synthesis of (Z)-5-arylmethylidene rhodanines as anti-methicillin-resistant Staphylococcus aureus (MRSA) agent. It can also be used in the preparation of 2-(3,4-dichlorophenoxy)-N-(2-morpholin-4-ylethyl)acetamide for the treatment of inflammatory pain.

The disappearance rates of 2,4- and 3,4-dichlorophenol in a small stream were studied and were shown to be first order with respect to either distance or time of flow. Both chlorophenols disappeared at approximately the same rate with average half-lives

The reductive dechlorination of pentachlorophenol (PCP) was investigated in anaerobic sediments that contained nonadapted or 2,4- or 3,4-dichlorophenol (DCP)-adapted microbial communities. Adaptation of sediment communities increased the rate of conversion of 2,4- or 3,4-DCP to monochlorophenols (CPs) and eliminated the
