N,N'-Bis-diisopentylmethylen-meso-1,2-diphenyl-α-ethylendiamin, also known as Chimassorb 81, is a Hindered Amine Light Stabilizer (HALS) used primarily in the plastics industry to protect materials from degradation caused by exposure to light, heat, and oxygen. This chemical is characterized by its ability to prevent discoloration and maintain the physical properties of polymers over time. It is particularly effective in polyolefins and other materials where it forms a stable radical that can neutralize harmful free radicals, thus extending the service life of the material. The compound's structure, with its diisopentylmethylen groups and central α-ethylendiamin moiety, contributes to its high efficiency and compatibility with a wide range of polymers.

1261-93-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1261-93-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,6 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.Calculate Digit Verification of CAS Registry Number 1261-93:
(6*1)+(5*2)+(4*6)+(3*1)+(2*9)+(1*3)=64
64 % 10 = 4
So 1261-93-4 is a valid CAS Registry Number.
