"4,4'-Dimethyl-1,1'-biphenyl-2,2',5,5'-tetraone" is a chemical compound with a molecular formula C16H10O4. It is a type of biphenyl tetraone derivative, which means it contains a central biphenyl ring with four ketone groups attached to the carbon atoms. 4,4'-Dimethyl-1,1'-biphenyl-2,2',5,5'-tetraone is a bright yellow solid with a high melting point and is insoluble in water. It is mainly used as a building block for the synthesis of other organic compounds and as a reactant in chemical reactions. Its unique molecular structure and reactivity make it useful in various fields of organic chemistry, including pharmaceuticals, materials science, and chemical synthesis.
Check Digit Verification of cas no
The CAS Registry Mumber 4388-07-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,8 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4388-07:
(6*4)+(5*3)+(4*8)+(3*8)+(2*0)+(1*7)=102
102 % 10 = 2
So 4388-07-2 is a valid CAS Registry Number.

Substituent effects in the oxidation of 2-alkyl-1,4-dialkoxybenzenes with ceric ammonium nitrate
Love, Brian E.,Simmons, Alexander L.
, p. 5712 - 5715 (2016/11/29)
Increased steric size of alkyl groups and the presence of coordinating atoms on alkoxy groups have both been found to contribute to decreasing yields of diquinones upon reaction of 2-alkyl-1,4-dialkoxybenzenes with CAN. The overall hydrophilicity of the substrates does not appear to be a significant factor in determining the diquinone yield for these reactions.
Improved synthesis of diquinones
Love, Brian E.,Bonner-Stewart, Jeffrey,Forrest, Lori A.
body text, p. 813 - 817 (2009/06/19)
Preparation of a series of substituted diquinones is reported. In most examples, inverse order of addition (addition of a dimethoxybenzene derivative to a CAN solution) has been found to produce higher yields of diquinones than the traditional protocol in which the oxidant is added to the arene.
