BDE 99

Description:

BDE 99, or 2,2',4,4',5-pentabromodiphenyl ether, is a brominated flame retardant belonging to the class of polybrominated diphenyl ethers (PBDEs). It is characterized by its high thermal stability and effectiveness in reducing flammability in various materials, particularly plastics and textiles. BDE 99 is a colorless to pale yellow solid at room temperature and is relatively insoluble in water but soluble in organic solvents. Its molecular structure consists of two phenyl rings connected by an ether linkage, with five bromine atoms substituted at specific positions on the rings. While BDE 99 has been widely used in consumer products, concerns have arisen regarding its environmental persistence, bioaccumulation potential, and potential adverse health effects, including endocrine disruption. As a result, many countries have implemented regulations to limit or ban its use. The substance is typically analyzed in environmental samples and biological tissues to assess exposure levels and ecological impact.
