Widely used in organic synthesis as a reagent for the formation of carbon-carbon and carbon-heteroatom bonds. It is particularly valuable in the preparation of ylides and as a precursor for various cycloaddition reactions. Commonly employed in the synthesis of complex organic molecules, including pharmaceuticals and natural products, due to its ability to facilitate efficient and selective transformations. Additionally, it serves as a key intermediate in the development of advanced materials and polymers, contributing to innovations in material science.
