Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of agrochemicals and bioactive molecules. Its sulfonyl ester functionality enables it to participate in nucleophilic substitution reactions, making it valuable for constructing carbon-carbon bonds in complex organic structures. Commonly employed in medicinal chemistry for modifying molecular properties such as solubility, metabolic stability, and target binding affinity. Also utilized in the preparation of sulfone-containing analogs for structure-activity relationship (SAR) studies.
