Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the development of sulfone-based drugs. It serves as a building block in organic reactions where sulfide functionality is required for further oxidation or coupling processes. Its acetyl group allows for additional functionalization, making it valuable in creating complex molecules for medicinal chemistry research. Also employed in the preparation of specialty polymers and optoelectronic materials due to its aromatic and sulfur-containing structure.
