4-Acetoxy-3,5,2',4',6'-pentamethyl-diphenyl-methan, also known as pentamethyldiphenylmethan or PMDM, is a complex organic compound with the chemical formula C20H24O2. It is a colorless, crystalline solid that is widely used as a UV stabilizer and light stabilizer in various applications, including plastics, coatings, adhesives, and elastomers. PMDM is effective in protecting materials from the harmful effects of ultraviolet radiation, which can cause degradation, discoloration, and loss of mechanical properties. The compound's molecular structure features two phenyl rings connected by a methylene bridge, with five methyl groups attached to the phenyl rings and an acetoxy group at the 4-position. Its chemical stability, low volatility, and compatibility with various polymers make it a popular choice for industrial use in preventing the deterioration of materials exposed to sunlight or artificial light sources.

4276-72-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4276-72-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,7 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.Calculate Digit Verification of CAS Registry Number 4276-72:
(6*4)+(5*2)+(4*7)+(3*6)+(2*7)+(1*2)=96
96 % 10 = 6
So 4276-72-6 is a valid CAS Registry Number.
