Cumyl-peroxymethacrylat, also known as 2,2'-azobis(2-methylpropionitrile), is a chemical compound widely used as a free radical initiator in the polymerization process of various materials, including acrylic and methacrylic resins. It is an efficient initiator for the production of polymers, offering a controlled rate of polymerization and improved product quality. The compound is characterized by its ability to decompose at relatively low temperatures, generating free radicals that initiate the polymerization reaction. Cumyl-peroxymethacrylat is also known for its stability and low toxicity, making it a preferred choice in many industrial applications.
The CAS Registry Mumber 4251-33-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,5 and 1 respectively; the second part has 2 digits, 3 and 3 respectively. Calculate Digit Verification of CAS Registry Number 4251-33: (6*4)+(5*2)+(4*5)+(3*1)+(2*3)+(1*3)=66 66 % 10 = 6 So 4251-33-6 is a valid CAS Registry Number.
