Used as a reagent in organic synthesis, particularly in the formation of sulfur-containing compounds. Acts as a nitrophenyl transfer agent in cross-coupling reactions. Employed in the development of pharmaceutical intermediates where disulfide and nitro groups play a role in bioactivity. Also applied in materials science for synthesizing specialty polymers with enhanced thermal or oxidative stability due to the presence of aromatic nitro and disulfide linkages. Its photoresponsive nature makes it useful in light-sensitive chemical systems.
