Dibutyl phosphate is be used as a precursor for antistatics, a mold release agent in polyurethane applications, and a non-volatile acidic catalyst in organic media. It is also used in many industrial applications as a surfactant because of its exceptional properties of wetting, emulsification, lubrication, coupling activity and detergency. Biologically Dibutyl phosphate is used as a diagnostic urine marker for exposure to certain toxic alkyl-phosphate compounds found in insecticides and industrial lubricants.
