Used as an intermediate in the synthesis of organophosphorus compounds, particularly in the preparation of phosphine ligands for catalysis. It plays a key role in the pharmaceutical industry for constructing bioactive molecules and in agrochemicals for developing pesticides with targeted activity. Its reactivity allows for the introduction of dimethylphosphinyl groups into organic frameworks, enhancing the efficiency of complex molecule assembly. Also utilized in flame retardant formulations due to the phosphorus content, contributing to fire resistance in polymers and materials.
