Used as a reagent in organic synthesis, particularly in the formation of phosphorylated compounds. It acts as a cyclization agent for the preparation of cyclic phosphoramidates, which are important in the development of biologically active molecules, including pharmaceuticals and agrochemicals. Its structure allows for selective reactions with diols and hydroxy acids, making it valuable in the synthesis of phosphate-containing heterocycles. Additionally, it serves as a precursor in the preparation of ligands for catalysis and in the modification of nucleotides for medicinal chemistry research.
