It is a colorless to pale yellow crystalline solid that is insoluble in water but soluble in organic solvents. Bis-<2-methyl-2-phenyl-vinyl>-ether is characterized by its symmetrical structure, featuring two phenyl groups connected to a central oxygen atom through vinyl groups. It is used as a stabilizer for polymers, particularly in the production of polyvinyl chloride (PVC), to prevent degradation and improve the material's stability and durability. Bis-<2-methyl-2-phenyl-vinyl>-ether is also known for its low volatility and non-toxic properties, making it a preferred choice in various industrial applications.
The CAS Registry Mumber 5530-34-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,3 and 0 respectively; the second part has 2 digits, 3 and 4 respectively. Calculate Digit Verification of CAS Registry Number 5530-34: (6*5)+(5*5)+(4*3)+(3*0)+(2*3)+(1*4)=77 77 % 10 = 7 So 5530-34-7 is a valid CAS Registry Number.
