Used primarily in organic synthesis as an intermediate for the preparation of various pharmaceuticals and agrochemicals. It serves as a building block in the development of bioactive molecules due to the presence of both nitro and arsonic acid functional groups, which can be selectively modified. Employed in research settings for the synthesis of novel arsenic-containing compounds with potential biological activity. Also finds use in coordination chemistry as a ligand for metal complexes, aiding in the study of metal-mediated reactions.
