2,3,5,6,2',3',5',6'-Octamethyl-benzil is a complex organic compound characterized by its molecular formula C20H24O2. It is a symmetrical molecule with a benzil core, which is essentially a diphenyl ketone, where two phenyl rings are connected by a carbonyl group. In this specific compound, each of the phenyl rings has four methyl groups attached to it, resulting in a highly branched and non-planar structure. The methyl groups are positioned at the 2, 3, 5, and 6 positions on both the central carbonyl carbons and the phenyl rings, leading to a significant increase in steric hindrance. 2,3,5,6,2',3',5',6'-Octamethyl-benzil is known for its stability and resistance to chemical reactions due to the electron-donating nature of the methyl groups, which can also influence its physical properties such as melting point and solubility. It is typically synthesized through a Friedel-Crafts acylation reaction and can be used in various applications, including as a precursor in the synthesis of other organic compounds or as a chemical intermediate in the pharmaceutical and chemical industries.
The CAS Registry Mumber 4746-83-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,4 and 6 respectively; the second part has 2 digits, 8 and 3 respectively. Calculate Digit Verification of CAS Registry Number 4746-83: (6*4)+(5*7)+(4*4)+(3*6)+(2*8)+(1*3)=112 112 % 10 = 2 So 4746-83-2 is a valid CAS Registry Number.
