General description

1,2,5,6,9,10-Hexabromocyclododecane(HBCD) is a brominated flame retardant. It is used in the textile industry and polystyrene foam manufacturing. Electrochemical reduction of HBCD at carbon and silver cathodes has been studied using cyclic voltammetry and controlled-potential electrolysis.

application

1,2,5,6,9,10-Hexabromocyclododecane(HBCD) was used to compare the efficiency of different advanced extraction techniques for the recovery of brominated flame retardants from styrenic polymers. It was used to study the kinetics of the thermal and photolytic segregation of HBCD using HPLC.

Biochem/physiol Actions

1,2,5,6,9,10-Hexabromocyclododecane enhances the diet-induced body weight gain and metabolic dysfunction via disruption of lipid and glucose homeostasis in mice fed normal diet or high-fat diet.
