2,2',4,4',6,6'-hexabromobiphenyl

Description:

2,2',4,4',6,6'-hexabromobiphenyl is a synthetic organic compound belonging to the class of polybrominated biphenyls (PBBs), which are brominated flame retardants. This compound features six bromine atoms substituted on a biphenyl structure, significantly altering its physical and chemical properties. It is typically a white to off-white solid with low solubility in water but higher solubility in organic solvents. Due to its brominated nature, it exhibits high thermal stability and resistance to degradation, making it effective as a flame retardant. However, PBBs, including hexabromobiphenyl, are known for their persistence in the environment and potential bioaccumulation in living organisms, raising concerns regarding their ecological and health impacts. They have been associated with various adverse effects, including endocrine disruption and developmental toxicity. Regulatory measures in many countries have restricted or banned the use of PBBs in consumer products, reflecting growing awareness of their environmental and health risks.
