2,3,4,4',5-pentabromobiphenyl

Description:

2,3,4,4',5-pentabromobiphenyl is a polybrominated biphenyl (PBB) compound characterized by the presence of five bromine atoms attached to a biphenyl structure. This compound is typically used as a flame retardant in various applications, including plastics and textiles, due to its ability to inhibit combustion. It is a solid at room temperature and exhibits low solubility in water, which is common for many brominated compounds. The presence of multiple bromine atoms contributes to its hydrophobic nature and can also affect its environmental persistence and bioaccumulation potential. 2,3,4,4',5-pentabromobiphenyl is subject to regulatory scrutiny due to concerns about its toxicity and potential effects on human health and the environment. It may disrupt endocrine functions and has been associated with various adverse health effects in laboratory studies. As a result, its use is increasingly restricted in many regions, reflecting a broader trend towards reducing reliance on halogenated flame retardants.
