Dibenzyl (chloromethyl) phosphate is primarily used as a reactive intermediate in organic synthesis, particularly in the preparation of phosphate esters. These esters are valuable in the development of flame retardants, which are incorporated into materials like plastics, textiles, and coatings to enhance fire resistance. Additionally, it serves as a key building block in the synthesis of biologically active compounds, including pharmaceuticals and agrochemicals, where phosphate-containing molecules play a critical role in drug delivery and activity. Its application also extends to the production of specialty chemicals used in research and industrial processes, contributing to advancements in material science and chemical engineering.
