32014-70-3 Usage
Uses
5,6-Diaminouracil sulfate is an intermediate in the synthesis of Paraxanthine (P192500) and Paraxanthine analogs.
Purification Methods
The salt is quite insoluble in H2O but can be converted to the free base which is recrystallised from H2O and converted to the sulfate by addition of the required amount of H2SO4. The hydrochloride has m 300-305o(dec) and can be used to prepare the sulfate by addition of H2SO4; it is more soluble than the sulfate. The perchlorate has m 252-254o. The free base has max at 260nm (log 4.24) in 0.1M HCl. [Bogert & Davidson J Am Chem Soc 86 1668 1933, Bredereck et al.

Check Digit Verification of cas no
The CAS Registry Mumber 32014-70-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,0,1 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 32014-70:
(7*3)+(6*2)+(5*0)+(4*1)+(3*4)+(2*7)+(1*0)=63
63 % 10 = 3
So 32014-70-3 is a valid CAS Registry Number.
