Description

2,3',4,4'-Tetrabromodiphenyl Ether CAS NO 189084-61-5 is a specific brominated aromatic compound belonging to the polybrominated diphenyl ether (PBDE) family. This chemical is valued for its role as a flame retardant intermediate and a critical standard for analytical and environmental testing. It is primarily required by manufacturers and research laboratories in the polymer, electronics, and environmental monitoring sectors for quality control and regulatory compliance purposes.

Application

• As a reference standard for the analysis and quantification of brominated flame retardants in environmental and biological samples.
• An intermediate in the synthesis of specialized flame-retardant formulations for polymers and plastics.
• Used in research and development to study the environmental fate, transport, and toxicology of PBDE congeners.
• For quality control in laboratories to calibrate analytical equipment such as GC-MS and HPLC systems.
• In the production of flame-retardant additives for applications in electronics, textiles, and construction materials.
• As a chemical reagent in organic synthesis for introducing brominated aromatic structures.
