Urea, N,N'-bis[2,4-bis(1,1-dimethylethyl)-6-(1-methylethyl)phenyl]-, also known as bisphenol A di-(2-hydroxyethyl) ether, is a complex organic compound with the chemical formula C27H42N2O2. It is a derivative of bisphenol A, a well-known chemical used in the production of polycarbonate plastics and epoxy resins. Urea, N,N'-bis[2,4-bis(1,1-dimethylethyl)-6-(1-methylethyl)phenyl]- is characterized by its two urea groups connected to a central bisphenol A structure, with each urea group featuring a 2,4-bis(1,1-dimethylethyl)-6-(1-methylethyl)phenyl moiety. It is used as a curing agent for epoxy resins, enhancing their mechanical properties and thermal stability. Due to its structural complexity and specific applications, it is an important chemical in the field of polymer chemistry and material science.
The CAS Registry Mumber 61899-10-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,8,9 and 9 respectively; the second part has 2 digits, 1 and 0 respectively. Calculate Digit Verification of CAS Registry Number 61899-10: (7*6)+(6*1)+(5*8)+(4*9)+(3*9)+(2*1)+(1*0)=153 153 % 10 = 3 So 61899-10-3 is a valid CAS Registry Number.
