Used as an intermediate in the synthesis of organophosphorus compounds, particularly in the development of agrochemicals and pesticides. Its reactive functional groups enable the formation of complex thiophosphoryl derivatives, which are valuable in creating insecticides and plant growth regulators. Also investigated for use in specialty flame retardants due to the phosphorus and chlorine content, contributing to thermal stability and fire resistance in polymers. Limited solubility in water but effective in organic solvent-based systems for industrial applications.
