C12Br10

C12Br10, commonly known as decabromodiphenyl ether, is a brominated flame retardant chemical compound. It belongs to the class of polybrominated diphenyl ethers (PBDEs), which are synthetic organobromine compounds designed to reduce flammability in various materials. The chemical structure consists of two phenyl rings connected by an ether linkage, with ten bromine atoms attached to the aromatic rings.

Decabromodiphenyl ether was widely used in the mid-20th century as a flame retardant in plastics, textiles, electronics, and other consumer products. Its effectiveness in reducing fire hazards made it a popular choice in industries where fire safety was critical. However, concerns about its environmental persistence, bioaccumulation, and potential toxicity have led to restrictions and bans in many countries.

Due to its high bromine content, C12Br10 is highly effective at inhibiting combustion but also exhibits properties that contribute to its persistence in the environment. It can degrade slowly and accumulate in living organisms, particularly in fatty tissues, leading to concerns about ecological and human health impacts. Studies have suggested potential links to endocrine disruption and developmental issues, though further research is ongoing.

Regulatory bodies, including the European Union’s REACH program and the United States Environmental Protection Agency (EPA), have imposed restrictions on its use. In some regions, it has been phased out in favor of alternative flame retardants with lower environmental and health risks. Despite its declining use, C12Br10 remains detectable in environmental samples, indicating its lingering presence in ecosystems.
