2,2',3,4'-Tetrachlorobiphenyl(CAS: 36559-22-5)

2,2',3,4'-Tetrachlorobiphenyl is a solid with a crystalline form. It has a molecular weight of approximately 305.99 g/mol and is poorly soluble in water but soluble in organic solvents like benzene and chloroform. Chemically, it is relatively stable but can undergo photodegradation. It has a melting point of around 170-175°C and is not highly reactive under normal conditions.

2,2',3,4'-Tetrachlorobiphenyl can be synthesized by chlorinating biphenyl in the presence of iron(III) chloride and phosphoric acid as catalysts. The reaction typically proceeds under reflux conditions, leading to a high yield of the desired product with good selectivity.

2,2',3,4'-Tetrachlorobiphenyl has been used in various industries, including the production of certain types of dyes and pigments, as well as in the manufacturing of electronic components and as a precursor for other chlorinated compounds. Its use is limited due to environmental and health concerns, and it is no longer produced for commercial use in many countries.

When handling 2,2',3,4'-Tetrachlorobiphenyl, it is essential to wear appropriate personal protective equipment (PPE), including gloves, safety goggles, and protective clothing. Work should be conducted in a well-ventilated area or in a fume hood. If a spill occurs, it should be handled carefully using appropriate containment and cleaning materials. Always consult the Material Safety Data Sheet (MSDS) for detailed information and emergency procedures.
