Source: Primarily used as an insecticide and deodorizer, it also has many manufacturing applications.

Summary: 1,4-dichlorobenzene is one of three dichlorobenzene isomers, with the chlorine atoms in the para configurations. It is primarily used as an insecticide, soil fumigant, and a deoderizer. It also used in the production process of plastic and electronics, as well as dyes. It is soluble in water up to 81.3 mg/L and has a density of 1.2475 g/mL at 25 C. Upon decomposition it produces gaseous hydrogen chloride and carbon oxides. It is classified by the EPA as a Hazardous Air Pollutant (HAPs). It exists in the vapor-phase in the atmosphere with a half-life of 40 days. It will have moderate mobility within soil based on Koc values ranging from 273 – 390. Volatilization from soil and water is expected to be a major method of removal. Bioaccumulation in organisms may be moderate to high.
