N,N'-Bis-β,β'-diphenyl-isopropyliden-meso-1,2-diphenyl-aethylendiamin, also known as N,N'-Bis(3,5-di-tert-butyl-4-hydroxyphenylpropionyl)-1,2-bis(4-hydroxyphenyl)ethane, is a complex organic compound with the molecular formula C44H48N2O4. It is a white crystalline powder that is widely used as an antioxidant and stabilizer in various industrial applications, particularly in the polymer and plastic industries. This chemical is known for its ability to prevent the degradation of polymers caused by heat, light, and oxygen, thereby extending the lifespan and maintaining the quality of the materials. Its structure features two phenyl groups connected by an ethylenediamine bridge, with each phenyl group being substituted by a diphenyl-isopropyliden group, which contributes to its stability and effectiveness as an antioxidant.
The CAS Registry Mumber 3190-20-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,9 and 0 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 3190-20: (6*3)+(5*1)+(4*9)+(3*0)+(2*2)+(1*0)=63 63 % 10 = 3 So 3190-20-3 is a valid CAS Registry Number.
