Usage

Description

3,3',5,5'-tetrabromo[1,1'-biphenyl]-2,2'-diol, commonly known as tetrabromobisphenol A (TBBPA), is a flame retardant chemical compound belonging to the bisphenol family. It is widely used in various products such as electronics, construction materials, and textiles to enhance their fire resistance. However, its presence in the environment and human tissues has raised concerns about its potential health effects, as it has been found to possess endocrine-disrupting properties and is associated with adverse effects on reproductive and developmental processes. TBBPA is also considered persistent and bioaccumulative in the environment, which may lead to long-term exposure and impacts on ecosystems.
