Used as a key intermediate in organic synthesis, particularly in the preparation of sulfonate esters for cross-coupling reactions. Its bromomethyl group enables alkylation of nucleophiles, while the trifluoromethylsulfonyl moiety acts as a strong electron-withdrawing group, enhancing reactivity in substitution reactions. Commonly employed in the development of pharmaceuticals and agrochemicals due to its ability to introduce functional handles for further derivatization. Also utilized in the synthesis of ligands and catalysts where controlled reactivity and stability are required.
