Bis-<4-(4-tert-amyl-phenoxy)-phenyl>-aether, also known as 1,1'-(oxybis(4,1-phenylene))bis(4-tert-amylphenol), is a complex organic compound with the chemical formula C30H38O2. It is a white crystalline solid that is insoluble in water but soluble in organic solvents. Bis-<4-(4-tert-amyl-phenoxy)-phenyl>-aether is characterized by its symmetrical structure, featuring two phenol groups connected by an ether linkage, with each phenol group substituted by a 4-tert-amyl group. It is often used as a stabilizer in polymers and plastics, particularly in the production of polyvinyl chloride (PVC), to prevent degradation caused by heat and light exposure. The compound's molecular structure and properties make it effective in protecting materials from oxidative stress, thus extending their service life and maintaining their integrity.
The CAS Registry Mumber 3983-86-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,8 and 3 respectively; the second part has 2 digits, 8 and 6 respectively. Calculate Digit Verification of CAS Registry Number 3983-86: (6*3)+(5*9)+(4*8)+(3*3)+(2*8)+(1*6)=126 126 % 10 = 6 So 3983-86-6 is a valid CAS Registry Number.
