Biphenyl-2,4'-dicarboxylic acid, also known as 4,4'-biphenyl dicarboxylic acid, is an organic compound with the chemical formula C14H10O4. It is a white crystalline solid that is soluble in organic solvents and has a melting point of approximately 300°C. biphenyl-2,4'-dicarboxylic acid is a derivative of biphenyl, with two carboxylic acid groups attached to the 2 and 4' positions of the biphenyl core. Biphenyl-2,4'-dicarboxylic acid is used as a monomer in the production of various polymers, such as poly(ether-imide)s and poly(ester-imide)s, which are known for their high thermal stability, mechanical strength, and chemical resistance. These polymers find applications in aerospace, automotive, and electronics industries. Additionally, biphenyl-2,4'-dicarboxylic acid can be used as a building block in the synthesis of other complex organic molecules and pharmaceuticals.

4445-50-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4445-50-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,4 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4445-50:
(6*4)+(5*4)+(4*4)+(3*5)+(2*5)+(1*0)=85
85 % 10 = 5
So 4445-50-5 is a valid CAS Registry Number.

Liquid-Phase Catalytic Oxidation of 2,4-Dimethylbiphenyl

Koshel',Lebedeva,Rudkovskii,Krestinina,Koshel',Danilova

, p. 55 - 59 (2007/10/03)

2,4-Dimethylbiphenyl synthesized by alkylalion of m-xylene with cyclohexanol and subsequent dehydrogenation was oxidized catalytically in the liquid phase to 2,4-biphenyldicarboxylic acid. The effects of temperature, the catalyst, and initial concentrations of reactants on the rate and efficiency of the process were studied.
