2,2'-Dianilino-azobenzol, also known as 4,4'-diaminoazobenzene, is an organic compound characterized by its azo group (-N=N-) connecting two aniline (phenylamine) groups. This yellow crystalline solid is a synthetic dye used in various applications, including the production of pigments and as an intermediate in the synthesis of other dyes. It is known for its chemical formula C12H12N4, and it exhibits a melting point of approximately 132-134°C. Due to its potential health risks, including carcinogenic properties, handling 2,2'-Dianilino-azobenzol requires appropriate safety measures, such as wearing protective clothing and using proper ventilation.
The CAS Registry Mumber 2074-94-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,7 and 4 respectively; the second part has 2 digits, 9 and 4 respectively. Calculate Digit Verification of CAS Registry Number 2074-94: (6*2)+(5*0)+(4*7)+(3*4)+(2*9)+(1*4)=74 74 % 10 = 4 So 2074-94-4 is a valid CAS Registry Number.
