m-Dibromobenzene is primarily used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals, agrochemicals, and specialty chemicals. It serves as a building block for creating complex molecules due to its reactive bromine atoms, which facilitate various substitution and coupling reactions. In the pharmaceutical industry, it is utilized in the synthesis of active pharmaceutical ingredients (APIs) and other bioactive compounds. Additionally, it finds application in the development of flame retardants and polymers, where its bromine content enhances fire resistance properties. Its role in research and development is also notable, as it is employed in the study of organic reactions and material science.
