Used primarily as an intermediate in the synthesis of dyes and pharmaceuticals. It serves in organic research for constructing more complex aromatic compounds due to the reactivity of the dinitro groups. Its hydroxyl and aromatic functionalities allow for derivatization in the development of sensors and analytical reagents. Also employed in the preparation of energetic materials because of the presence of nitro groups, which contribute to high energy density. Handling requires caution due to potential instability under heat or shock.
