3,3'-Dinitrobenzophenone is primarily used in the synthesis of specialty chemicals and intermediates in organic chemistry. It serves as a key precursor in the production of dyes, pigments, and pharmaceuticals, where its nitro groups facilitate further chemical transformations. Additionally, it is employed in research and development for creating complex organic compounds, particularly in studies involving nitroaromatic chemistry. Its stability and reactivity make it valuable in industrial applications where controlled nitration processes are required.
