Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and fine chemicals. Its sulphonyl functional group enables participation in coupling reactions and sulfonamide formation, making it valuable in drug development. Commonly employed in the synthesis of anti-inflammatory agents and kinase inhibitors due to its ability to enhance molecular stability and binding affinity. Also utilized in the preparation of photoinitiators for polymer chemistry, where it contributes to light-induced curing processes in coatings and adhesives.
