Summary: Methoxychlor is a synthetic compound formerly used as an insecticide. It has been banned for use as a pesticide in the United States since 2004. It is soluble in water up to 0.040 mg/L at 24 C and has a density of 1.41 g/mL at 25 C. Upon decomposition it produces hydrogen chloride gas. Methoxychlor is classified by the EPA as a Hazardous Air Pollutant (HAPs). Koc values ranging from 23,000 – 93,000 indicate that the compound will have low to no mobility within soil. It is resistant to aerobic biodegradation but is susceptible under anaerobic conditions. Bioaccumulation in organisms is expected to be very high.
