CAS 39635-79-5: Tetrabromobisphenol S

Description: Tetrabromobisphenol S (TBBPS) is a brominated flame retardant characterized by its chemical structure, which includes two bisphenol units with four bromine atoms attached. It is primarily used in the production of epoxy resins and other polymeric materials to enhance their fire resistance. TBBPS is known for its high thermal stability and effectiveness in reducing flammability, making it valuable in various applications, including electronics, textiles, and construction materials. The substance is typically a white to off-white solid and is soluble in organic solvents but has limited solubility in water. TBBPS has raised environmental and health concerns due to its potential persistence in the environment and bioaccumulation in living organisms. Studies have indicated that it may exhibit endocrine-disrupting properties, prompting regulatory scrutiny. As a result, its use is being evaluated and monitored in many regions to mitigate potential risks associated with its production and application.
