Application

2,2'-Dibromobiphenyl is a white crystalline powder that serves a specific purpose in chemical synthesis by acting as a precursor in the production of 5,5-dimethyl-5H-dibenzosilole. This process takes place at temperatures ranging from -78 to 20°C and requires the use of the reagent n-BuLi along with solvents such as diethyl ether and hexane. As a member of the polybrominated biphenyls (PBBs), which consist of biphenyl compounds with attached bromine atoms, 2,2'-Dibromobiphenyl has historical use as a flame retardant in various materials, including plastics for electronics and textiles, due to its ability to reduce flammability. Despite this, the use of PBBs, including 2,2'-Dibromobiphenyl, is limited or banned in many jurisdictions because of their environmental persistence and potential toxicity.
