Used primarily in research and development, 3,5-Dibromo-biphenyl serves as a key intermediate in organic synthesis. It is often employed in the production of advanced materials, such as liquid crystals and polymers, due to its ability to introduce bromine atoms into complex molecules. This chemical is also utilized in the study of environmental pollutants, particularly in understanding the behavior and degradation of brominated compounds. Additionally, it finds application in the pharmaceutical industry for the synthesis of bioactive molecules and in the development of flame retardants for various industrial materials.
