591-54-8 Usage
Chemical Properties
White to slightly beige crystals or powder
Uses
4-Aminopyrimidine has been used in the preparation of 1:4-dihydro-4-imino-1-methylpyrimidine hydriodide.
General Description
The consequences of one-electron oxidation and one-electron reduction were studied for 4-aminopyrimidine.
Purification Methods
Recrystallise 10.6g of aminopyrimidine from hot EtOAc (200mL) to give 7.4g colourless needles as first crop; evaporation to 25mL gives a second crop of 1.7g. The hydroiodide has m 180o. The picrate has m 225o. [Brown J Soc Chem Ind (London) 69 353 1950, Beilstein 24 H 81, 24 III/IV 2130.]
Check Digit Verification of cas no
The CAS Registry Mumber 591-54-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 591-54:
(5*5)+(4*9)+(3*1)+(2*5)+(1*4)=78
78 % 10 = 8
So 591-54-8 is a valid CAS Registry Number.
