4,4′-bis(carboxyethenyl)-1,1′-biphenyl, also known as 4,4′-(1,1′-biphenyl)diacrylic acid or simply biphenyl diacrylate, is a synthetic organic compound characterized by a biphenyl core with two acrylic acid groups attached to the 4,4′ positions. This molecule is a white crystalline solid that is soluble in organic solvents and is commonly used as a cross-linking agent in polymer chemistry, particularly in the production of high-performance polymers and resins. Its unique structure allows it to form strong covalent bonds with other molecules, enhancing the mechanical properties and thermal stability of the resulting materials.
The CAS Registry Mumber 5649-92-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,4 and 9 respectively; the second part has 2 digits, 9 and 2 respectively. Calculate Digit Verification of CAS Registry Number 5649-92: (6*5)+(5*6)+(4*4)+(3*9)+(2*9)+(1*2)=123 123 % 10 = 3 So 5649-92-3 is a valid CAS Registry Number.
