Summary: Methyl parathion is an organophosphate used as a pesticide. It is no longer used in the United States. It is a synthetically produced compound that is soluble in water up to 37.7 mg/L at 20 C and has a density of 1.358 g/mL at 20 C. Upon decomposition it produces gaseous nitrogen/phosphorous/sulfur oxides. It has a pKa value of 7.15. Koc values ranging from 366 to 1516 indicate moderate to low mobility within soil. Biodegradation and hydrolysis are expected to be the main methods of natural removal from soil and water.
