Bis-<β-phenyl-isobutyryl>-peroxid, also known as bis(β-phenylisobutyryl) peroxide, is a chemical compound with the molecular formula C20H22O4. It is a white crystalline solid that is widely used as a polymerization initiator, particularly in the production of polystyrene and other vinyl polymers. Bis-<β-phenyl-isobutyryl>-peroxid is known for its ability to decompose at relatively low temperatures, releasing free radicals that initiate the polymerization process. It is also used as a curing agent for unsaturated polyester resins and as a cross-linking agent in various applications. Due to its reactivity, it is important to handle bis(β-phenylisobutyryl) peroxide with care, as it can be sensitive to heat, light, and impact, and may pose a risk of explosion if not stored and used properly.

Check Digit Verification of cas no
The CAS Registry Mumber 4249-87-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,4 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.Calculate Digit Verification of CAS Registry Number 4249-87:
(6*4)+(5*2)+(4*4)+(3*9)+(2*8)+(1*7)=100
100 % 10 = 0
So 4249-87-0 is a valid CAS Registry Number.
