5,5'-di-tert-butyl-4,4'-dimethoxy-2,2'-methanediyl-di-phenol is a complex organic compound with the molecular formula C22H32O4. It is a derivative of bisphenol A, featuring two phenol groups connected by a methanediyl bridge. The compound is characterized by the presence of two tert-butyl groups at the 5,5' positions, which provide steric hindrance and contribute to its stability. Additionally, it has two methoxy groups at the 4,4' positions, enhancing its solubility and reactivity. 5,5'-di-tert-butyl-4,4'-dimethoxy-2,2'-methanediyl-di-phenol is often used as a precursor in the synthesis of polymers, such as polycarbonates and epoxy resins, due to its ability to form stable, high-molecular-weight products. Its chemical structure also imparts thermal and oxidative stability to the resulting polymers, making it a valuable component in various industrial applications.
The CAS Registry Mumber 5288-44-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,8 and 8 respectively; the second part has 2 digits, 4 and 4 respectively. Calculate Digit Verification of CAS Registry Number 5288-44: (6*5)+(5*2)+(4*8)+(3*8)+(2*4)+(1*4)=108 108 % 10 = 8 So 5288-44-8 is a valid CAS Registry Number.
