Used as a reagent in organic synthesis, particularly in the Wittig reaction, to convert carbonyl compounds into alkenes. It is valuable in the preparation of complex organic molecules, including pharmaceuticals and natural products. The compound acts as a precursor for generating ylides, which are essential intermediates in carbon-carbon bond formation. Its application extends to the development of fine chemicals and specialized materials, where precise control over molecular structure is required. Additionally, it is employed in research settings to study reaction mechanisms and explore new synthetic pathways.
