70239-82-6 Usage
Uses
Used in Fluorocarbon Elastomer Industry:
Phenol, 2-amino-4-ethynyl(9CI) is used as an end-capping agent for fluorocarbon ether oligomers containing terminal imidate groups. This application is crucial in the preparation of fluorocarbon elastomers, which are known for their exceptional chemical resistance, thermal stability, and non-stick properties. The use of Phenol, 2-amino-4-ethynyl(9CI) as an end-capping agent helps in controlling the molecular weight and improving the overall performance of the resulting fluorocarbon elastomers.
Check Digit Verification of cas no
The CAS Registry Mumber 70239-82-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,3 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 70239-82:
(7*7)+(6*0)+(5*2)+(4*3)+(3*9)+(2*8)+(1*2)=116
116 % 10 = 6
So 70239-82-6 is a valid CAS Registry Number.
