Synonyms: "2,3,4,4',5,6-hexabromodiphenyl ether", "BDE-166".

Source: pentabromo(4-bromophenoxy)benzene belongs to polybrominated diphenyl ethers (PBDEs), which are a class of recalcitrant and bioaccumulative halogenated compounds that have emerged as a major environmental pollutant. PBDEs are used as a flame-retardant and are found in consumer goods such as electrical equipment, construction materials, coatings, textiles and polyurethane foam (furniture padding).
