α,α'-dibromo-3,5,3',5'-tetra-tert-butyl-bibenzyl-4,4'-diol is a complex organic compound characterized by its unique molecular structure. It features a biphenyl core, which is a type of organic compound consisting of two benzene rings connected by a single bond. In this specific compound, the biphenyl core is substituted with two bromine atoms at the α positions (the carbon atoms directly attached to the benzene rings), and two hydroxyl groups at the 4,4' positions, which are the para positions relative to each other on the two benzene rings. Additionally, the compound has four tert-butyl groups attached to the 3,5,3', and 5' positions, which are the meta positions on the benzene rings. These tert-butyl groups are bulky, alkyl substituents that can significantly influence the compound's physical and chemical properties, such as its solubility and reactivity. The presence of these groups, along with the bromine atoms and hydroxyl groups, makes α,α'-dibromo-3,5,3',5'-tetra-tert-butyl-bibenzyl-4,4'-diol a potentially interesting molecule for various applications in chemistry, such as in the synthesis of pharmaceuticals or materials science.
The CAS Registry Mumber 98195-65-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,1,9 and 5 respectively; the second part has 2 digits, 6 and 5 respectively. Calculate Digit Verification of CAS Registry Number 98195-65: (7*9)+(6*8)+(5*1)+(4*9)+(3*5)+(2*6)+(1*5)=184 184 % 10 = 4 So 98195-65-4 is a valid CAS Registry Number.
