2,2′,5,5′-Tetrabromobiphenyl

Description:

2,2′,5,5′-Tetrabromobiphenyl is a brominated biphenyl compound characterized by the presence of four bromine atoms attached to the biphenyl structure. It is a member of the polybrominated biphenyl (PBB) family, which are known for their use as flame retardants. This compound is typically a solid at room temperature and exhibits low solubility in water, but it is soluble in organic solvents. Its molecular structure contributes to its stability and resistance to degradation, making it persistent in the environment. 2,2′,5,5′-Tetrabromobiphenyl has raised environmental and health concerns due to its potential toxicity and bioaccumulation in living organisms. It is subject to regulatory scrutiny, particularly regarding its impact on human health and ecosystems. The compound's properties, such as its melting point, boiling point, and specific reactivity, can vary based on its purity and the presence of other substances. Overall, 2,2′,5,5′-Tetrabromobiphenyl exemplifies the challenges associated with the use of brominated flame retardants in industrial applications.
