Hexabromocyclododecane (HBCD) is a brominated flame retardant that is primarily used in polystyrene foam insulation and other building materials. It is characterized by its chemical structure, which consists of a cyclododecane ring with six bromine atoms attached, contributing to its flame-retardant properties. HBCD is a white, crystalline solid that is insoluble in water but soluble in organic solvents. Its thermal stability and effectiveness in reducing flammability make it valuable in various applications, particularly in construction and electronics. However, HBCD has raised environmental and health concerns due to its persistence in the environment and potential bioaccumulation in living organisms. It has been classified as a substance of very high concern under the European Union's REACH regulation, leading to restrictions on its use in many regions. As a result, alternatives to HBCD are being explored in the industry to mitigate its environmental impact while maintaining fire safety standards.
