Used as a key intermediate in the synthesis of sulfur-containing heterocyclic compounds, particularly in the development of pharmaceuticals with antimicrobial and antitumor activities. It serves as a disulfide coupling agent in organic synthesis, enabling the formation of symmetrical and unsymmetrical disulfide bridges in bioactive molecules. Its benzo[d]thiazole moiety contributes to enhanced binding affinity with biological targets, making it valuable in medicinal chemistry for designing enzyme inhibitors. Also applied in materials science for developing functional polymers with redox-active properties.
