Used primarily as a reactive intermediate in organic synthesis, particularly in the preparation of sulfonamide derivatives. Its high reactivity makes it valuable in pharmaceutical manufacturing, where it serves as a building block for bioactive molecules. Commonly employed in ring-strain-driven reactions, it enables the formation of complex cyclic structures. Also utilized in agrochemical synthesis and in the development of specialty polymers due to its ability to introduce cyclobutane-based sulfonic acid groups. Handling requires caution due to its moisture sensitivity and potential for exothermic reactions.
