Bis-(1-methyl-1-p-tolyl-ethyl)-peroxide, also known as di(1-methyl-1-phenylethyl) peroxide, is an organic compound with the chemical formula C18H22O2. It is a colorless, crystalline solid that is soluble in organic solvents. This peroxide is commonly used as a polymerization initiator, particularly in the production of polystyrene and other polymers. It is also employed as a cross-linking agent in the rubber industry. Due to its reactive nature, it is important to handle bis-(1-methyl-1-p-tolyl-ethyl)-peroxide with care, as it can decompose and release oxygen, posing a risk of explosion if not stored and used properly.
The CAS Registry Mumber 7664-82-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,6 and 4 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 7664-82: (6*7)+(5*6)+(4*6)+(3*4)+(2*8)+(1*2)=126 126 % 10 = 6 So 7664-82-6 is a valid CAS Registry Number.
