Usage

Uses

Used in Flame Retardancy:
2,6-DIBROMODIPHENYL ETHER is used as an additive in the plastics and textiles industry for its flame retardant properties. The addition of 2,6-DIBROMODIPHENYL ETHER to materials enhances their resistance to ignition and slows down the spread of fire, making them safer for consumer use.
Used in Electronic Components:
In the electronics industry, 2,6-DIBROMODIPHENYL ETHER is used as a flame retardant in the manufacturing of electronic components and casings. Its incorporation into these materials helps to reduce the risk of fire hazards and improve the overall safety of electronic devices.
Used in Environmental Remediation:
Although 2,6-DIBROMODIPHENYL ETHER is a flame retardant, it is also recognized as an environmental pollutant. As a result, it is used in environmental remediation efforts to mitigate the negative impacts of 2,6-DIBROMODIPHENYL ETHER on ecosystems and human health. This includes the development of strategies for its safe disposal and the reduction of its release into the environment.

Synthesis and characterization of 32 polybrominated diphenyl ethers

Polybrominated diphenyl ethers (PBDEs) are widely used as additive flame retardants in, for example, textiles, computers, television sets, and other electrical appliances. present also in humans. The environmental levels of the PBDEs are, however, still in general lower than those of polychlorinated biphenyls (PCBs). However, while the levels of PCBs generally are decreasing, those of the PBDEs are increasing in, for example, human milk. In the present study 32 individual PBDE congeners were synthesized and characterized. Physicochemical parameters including melting points and UV, 1H NMR, and mass spectra are reported Twenty-nine monobrominated to heptabrominated diphenyl ethers were synthesized by the couping between four diphenyliodonium salts and nine phenolates. One tetrabromodiphenyl ether and two hexabromodiphenyl ethers were synthesized by bromination of two different PBDEs. Twenty-one of the PBDEs and two of the iodonium salts, 2,2′,4,4′-tetrabromodiphenyliodonium chloride and 3,3′,4,4′-tatrabromodiphenyliodonium chloride, are to the authors' knowledge described for the first time. These synthesized reference compounds will aid in the identification and quantification of PBDEs present in environmental samples and will allow further assessment of PBDE toxicity.
