3,3′,4,4′-Tetrabromodiphenyl ether

Description:

3,3′,4,4′-Tetrabromodiphenyl ether (CAS 93703-48-1) is a brominated flame retardant belonging to the class of diphenyl ethers. It is characterized by the presence of four bromine atoms attached to the diphenyl ether structure, which enhances its flame-retardant properties. This compound is typically used in various applications, including plastics, textiles, and electronics, to reduce flammability. It is a white to off-white solid at room temperature and is generally insoluble in water but soluble in organic solvents. The presence of bromine atoms contributes to its thermal stability and resistance to degradation. However, concerns have been raised regarding its environmental persistence and potential toxicity, as brominated compounds can bioaccumulate and may disrupt endocrine functions in living organisms. Regulatory scrutiny has increased around such substances, leading to restrictions in certain applications. Overall, while 3,3′,4,4′-Tetrabromodiphenyl ether serves important industrial functions, its environmental and health impacts warrant careful consideration.
