β,β-Divinyl-β-phenylethanol, also known as 3,4-Divinylbenzyl alcohol or 3,4-Divinylbenzyl alcohol, is an organic compound with the chemical formula C12H14O. It is a colorless to pale yellow liquid with a molecular weight of 174.24 g/mol. β,β-Divinyl-β-phenylethanol is characterized by the presence of two vinyl groups (C=C) attached to the β-carbon of a phenyl ring, with a hydroxyl group (-OH) attached to the β-carbon of the phenyl ring as well. It is used as a monomer in the synthesis of various polymers, particularly in the production of high-performance resins and specialty polymers. Due to its unique structure, β,β-Divinyl-β-phenylethanol contributes to the formation of cross-linked polymer networks, enhancing the mechanical properties and thermal stability of the resulting materials.
The CAS Registry Mumber 70178-99-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,1,7 and 8 respectively; the second part has 2 digits, 9 and 9 respectively. Calculate Digit Verification of CAS Registry Number 70178-99: (7*7)+(6*0)+(5*1)+(4*7)+(3*8)+(2*9)+(1*9)=133 133 % 10 = 3 So 70178-99-3 is a valid CAS Registry Number.
