Used as an intermediate in organic synthesis, particularly in the development of pharmaceutical compounds. It serves as a building block in the preparation of sulfonamide-based drugs, which are known for their antimicrobial and enzyme-inhibiting properties. Its structure allows for selective modifications, making it valuable in medicinal chemistry research for designing protease inhibitors and other bioactive molecules. Also employed in the study of reaction mechanisms involving sulfonamides due to its stability and reactivity profile.
