4318-76-7 Usage
Chemical Properties
Yellow to purple crystalline powder
Uses
2,5-Diaminopyridine may be used in the preparation of 6-acetamidoimidazo[ 1,2-a]pyridine. It may be used in the preparation of organo-soluble polyimides by reacting with different dianhydride monomers. These polyimides form the precursor for preparing novel polyimide-silica composites.
General Description
2,5-Diaminopyridine is a disubstituted pyridine that can be prepared by the reduction of 5-nitro-2-aminopyridine using 10%Pd/C.
Check Digit Verification of cas no
The CAS Registry Mumber 4318-76-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,1 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4318-76:
(6*4)+(5*3)+(4*1)+(3*8)+(2*7)+(1*6)=87
87 % 10 = 7
So 4318-76-7 is a valid CAS Registry Number.
