2,2',3,4,4',5,6-HEPTABROMODIPHENYL ETHER

Description:

2,2',3,4,4',5,6-Heptabromodiphenyl ether (CAS 189084-67-1) is a polybrominated diphenyl ether (PBDE) compound, characterized by the presence of seven bromine atoms attached to a diphenyl ether structure. This compound is part of a larger class of brominated flame retardants, which are used to reduce flammability in various materials, including plastics and textiles. Heptabromodiphenyl ether is known for its high thermal stability and effectiveness as a flame retardant. However, it raises environmental and health concerns due to its persistence in the environment, potential bioaccumulation, and possible toxic effects on human health and wildlife. It has been associated with endocrine disruption and neurodevelopmental issues. Regulatory measures in various countries have led to restrictions on the use of PBDEs, including heptabromodiphenyl ether, prompting research into safer alternatives. Its physical properties include a high molecular weight and low solubility in water, which contribute to its environmental persistence.
