Description

Chlorpyrifos (diethyl 3,5,6-trichloro-2-pyridyl phosphorothionate) is a white crystal-like solid with a strong odor. It does not mix well with water, so it is usually mixed with oily liquids before it is applied to crops or animals (ATSDR, 1997).
Chlorpyrifos belongs to the class of insecticides known as organophosphates. Technical chlorpyrifos is an amber to white crystalline solid with a mild sulfur odor. It is insoluble in water, but soluble in benzene, acetone, chloroform, carbon d
