2,2′,4,5,5′-Pentabromobiphenyl

Description:
2,2′,4,5,5′-Pentabromobiphenyl, with the CAS number 67888-96-4, is a synthetic organic compound belonging to the class of brominated biphenyls. It is characterized by the presence of five bromine atoms attached to a biphenyl structure, which consists of two phenyl rings connected by a single bond. This compound is typically used as a flame retardant due to its ability to inhibit combustion processes. Its physical properties include a high molecular weight and low volatility, which contribute to its persistence in the environment. 2,2′,4,5,5′-Pentabromobiphenyl is known for its lipophilicity, leading to bioaccumulation in living organisms. Additionally, it has raised environmental and health concerns due to its potential toxicity and endocrine-disrupting effects. Regulatory measures may restrict its use and promote safer alternatives in various applications, particularly in plastics and textiles. Overall, while it serves important industrial functions, its environmental impact necessitates careful management and assessment.
