133-63-1 Usage
Uses
Used in Rubber and Polymer Industry:
2,2'-methylenebis[6-tert-butylphenol] is used as a stabilizer for the production of rubber and other polymers, serving to prevent degradation caused by heat, oxygen, and ozone. Its presence enhances the durability and longevity of these materials.
Used in Lubricants and Fuels:
In the lubricants and fuels industry, 2,2'-methylenebis[6-tert-butylphenol] is utilized as an antioxidant. It helps to prevent the formation of harmful by-products, thereby improving the performance and extending the life of the lubricants and fuels in which it is incorporated.
Given its relatively non-hazardous nature and low acute toxicity, 2,2'-methylenebis[6-tert-butylphenol] is generally regarded as safe for use in industrial applications when handled and stored properly.
Check Digit Verification of cas no
The CAS Registry Mumber 133-63-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133-63:
(5*1)+(4*3)+(3*3)+(2*6)+(1*3)=41
41 % 10 = 1
So 133-63-1 is a valid CAS Registry Number.

[reaction: see text] Traditionally, asymmetric catalysts have been optimized by modification of resolved chiral ligands. In this Letter, we optimize the asymmetric addition of diethylzinc to aldehydes by modification of achiral methylene bis(phenol) ligands. Upon coordination of the substrate, the achiral ligand becomes asymmetric, a concept termed Metal Geometry-Induced Ligand Asymmetry. The enantioselectivity of the catalyst formed from a single resolved ligand and several achiral ligands ranged from 9% (R) to 83% (S).
