Used primarily in organic synthesis, it serves as a key intermediate for creating various sulfonamide derivatives. These derivatives are often employed in the development of pharmaceuticals, particularly in the design of drugs with antibacterial or anti-inflammatory properties. Additionally, it is utilized in the production of dyes and pigments, contributing to vibrant and stable colorants for industrial applications. Its reactivity with amines and other nucleophiles makes it valuable in constructing complex molecular structures in research and manufacturing.
