Used primarily as a sulfonylating agent in organic synthesis, enabling the introduction of the naphthalen-2-ylmethylsulfonyl group to various nucleophiles such as amines and alcohols. This modification is valuable in the development of pharmaceuticals and agrochemicals, where sulfonyl derivatives often enhance biological activity or metabolic stability. It serves as an intermediate in the preparation of sulfonamides, which are common motifs in drug design due to their role as enzyme inhibitors. Its aromatic and sulfonyl functionalities make it suitable for constructing complex molecules in medicinal chemistry research.
