4-Amino-2,2,5,5-tetramethyl-2,5-dihydro-1H-imidazol-1-ol 3-oxide is a chemical with a specific purpose. Lookchem provides you with multiple data and supplier information of this chemical.
The CAS Registry Mumber 91575-47-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,7 and 5 respectively; the second part has 2 digits, 4 and 7 respectively. Calculate Digit Verification of CAS Registry Number 91575-47: (7*9)+(6*1)+(5*5)+(4*7)+(3*5)+(2*4)+(1*7)=152 152 % 10 = 2 So 91575-47-2 is a valid CAS Registry Number.

The position of the tautomeric equilibrium in amino-, hydroxy-, and mercaptonitrones was determined by the 13C NMR method for the case of the derivatives of 3-imidazoline-3-oxide.It was shown that the tautomeric equilibrium in the OH and SH derivatives is shifted toward the oxo and thioxo forms (ca. 95percent).The chemical shifts of the carbon atoms of the nitrone group in the α-N-, α-O-, and α-S-substituted nitrones lie in the region of 137 - 150 ppm.
