Used as an intermediate in the synthesis of organophosphorus compounds, particularly in the development of flame retardants and plasticizers. Its reactivity allows for the introduction of phosphonate groups into larger molecules, enhancing thermal stability and fire resistance in polymers. Also employed in specialty coatings and adhesives where improved adhesion and durability are required. Shows potential in agrochemical formulations as a building block for active ingredients due to its ability to modify molecular polarity and bioavailability.
