Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of sulfone-containing compounds. Its ester and sulfonyl functional groups make it valuable in organic transformations, including carbon-chain elongation and Michael addition reactions. Commonly employed in the preparation of biologically active molecules due to its ability to introduce methylsulfonyl alkyl motifs, which can enhance metabolic stability and binding affinity in drug candidates. Also utilized in the manufacture of specialty chemicals requiring polar, electron-withdrawing groups for tailored reactivity.
