2,2',3,4',5,6-Hexachlorobiphenyl(CAS: 68194-13-8)

2,2',3,4',5,6-Hexachlorobiphenyl is a crystalline solid with a high molecular weight and limited solubility in common solvents. It is not very reactive under normal conditions. The compound has a melting point of approximately 300°C and is not readily biodegradable.

2,2',3,4',5,6-Hexachlorobiphenyl is typically synthesized through a series of chlorination reactions of biphenyl using chlorine gas as the chlorinating agent. The process involves multiple steps and requires careful control of reaction conditions to achieve high selectivity and yield.

2,2',3,4',5,6-Hexachlorobiphenyl was historically used in the production of flame retardants, but its use has been largely discontinued due to environmental concerns. However, it was once employed in the manufacturing of certain types of adhesives, sealants, and as a raw material for halogenated compounds.

When handling 2,2',3,4',5,6-Hexachlorobiphenyl, it is essential to use personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood. Spills should be cleaned up using appropriate procedures, and it is advisable to consult the Safety Data Sheet (SDS) for detailed instructions on handling and disposal.
