4',4'''-azo-bis-biphenyl-4-ylamine, also known as 4,4'-Azobis(4-aminobiphenyl), is an organic compound with the chemical formula C24H22N4. It is a yellow crystalline solid that is widely used as a chemical intermediate and a polymerization initiator. 4',4'''-azo-bis-biphenyl-4-ylamine is particularly effective in the production of polyamides, polyesters, and other polymers due to its ability to decompose at elevated temperatures, generating free radicals that initiate the polymerization process. It is also used in the rubber industry for the production of tires and other rubber goods. However, due to its potential health risks, including carcinogenic properties, its use is regulated, and safer alternatives are often sought in various applications.
The CAS Registry Mumber 2578-32-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,7 and 8 respectively; the second part has 2 digits, 3 and 2 respectively. Calculate Digit Verification of CAS Registry Number 2578-32: (6*2)+(5*5)+(4*7)+(3*8)+(2*3)+(1*2)=97 97 % 10 = 7 So 2578-32-7 is a valid CAS Registry Number.
