CAS No. 70851-50-2 is a chemical compound known as 3,3'-dichloroazobenzene. It is a white to off-white crystalline solid, with a melting point of 86-88 °C and a boiling point of 323-325 °C. It is soluble in organic solvents such as benzene, ethanol and acetone, but insoluble in water.

3,3'-Dichloroazobenzene, also known as 4,4'-dichloroazobenzene, is primarily used as an intermediate in the production of dyes and pigments. It is also used as an antioxidant in rubber compounding, a stabilizer in plastics and a curing accelerator in urethane foam production.

This product is highly toxic and can cause skin, eye and respiratory irritation. It is also a suspected carcinogen. For this reason, it should be handled with extreme caution, using appropriate protective equipment and procedures. It should be stored in a cool, dry and well-ventilated area, away from direct sunlight and other sources of heat.

In addition, 3,3'-dichloroazobenzene must be disposed of in accordance with applicable laws and regulations. It should not be released into the environment or placed into the waste stream without proper treatment.
