Used primarily in organic synthesis as a phosphorylating agent, it facilitates the introduction of phosphate groups into various molecules. This chemical is particularly valuable in the production of nucleotides and their analogs, which are crucial in biochemical research and pharmaceutical development. It also plays a role in the synthesis of insecticides and herbicides, contributing to agricultural chemistry. Additionally, it is employed in the modification of peptides and proteins, aiding in the study of their structure and function. Its reactivity with alcohols and amines makes it a versatile reagent in the preparation of phosphoramidates and phosphates, which have applications in drug design and material science.
