Used as an intermediate in organic synthesis, particularly in the preparation of dyes and pharmaceuticals. It serves in the development of nitroaromatic compounds which can be reduced to amino derivatives for use in drug manufacturing. Also applied in research settings for studying reaction mechanisms involving nucleophilic aromatic substitution due to the electron-withdrawing nitro group enhancing reactivity. Its sodium salt form improves water solubility, facilitating its use in aqueous-phase reactions.
