2,2',5,5'-tetra-tert-butylbiphenyl is an organic compound with the chemical formula C28H40. It is a derivative of biphenyl, which consists of two phenyl rings connected by a single bond. The compound is characterized by the presence of four tert-butyl groups (C4H9) attached to the biphenyl core, specifically at the 2, 2', 5, and 5' positions. This structure endows the molecule with a high degree of steric hindrance, which can affect its physical and chemical properties. 2,2',5,5'-tetra-tert-butylbiphenyl is known for its thermal stability and resistance to oxidation, making it a potential candidate for applications in materials science, such as in the development of high-performance polymers and as a stabilizer in various industrial processes.
The CAS Registry Mumber 97135-79-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,1,3 and 5 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 97135-79: (7*9)+(6*7)+(5*1)+(4*3)+(3*5)+(2*7)+(1*9)=160 160 % 10 = 0 So 97135-79-0 is a valid CAS Registry Number.
