4-amino-2-imino-5,5-dimethyl-2,5-dihydro-1H-imidazole 1-oxyl, also known as 4-amino-TEMPO, is a stable nitroxide radical with the chemical formula C6H12N3O. It is a derivative of imidazole, featuring an amino group at the 4-position, an imino group at the 2-position, and two methyl groups at the 5-position. 4-amino-2-imino-5,5-dimethyl-2,5-dihydro-1H-imidazole 1-oxyl is widely used as a spin label and a radical scavenger in various applications, including electron paramagnetic resonance (EPR) spectroscopy, as a catalyst in oxidation reactions, and in the synthesis of other nitroxide radicals. Its stability and reactivity make it a valuable tool in the field of chemistry, particularly in studies involving free radicals and their interactions with biomolecules.

Check Digit Verification of cas no

The CAS Registry Mumber 6418-48-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,1 and 8 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6418-48:
(6*6)+(5*4)+(4*1)+(3*8)+(2*4)+(1*8)=100
100 % 10 = 0
So 6418-48-0 is a valid CAS Registry Number.

Properties and structures of porphyrexides

Tretyakov,Bogomyakov,Fursova,Romanenko,Ikorskii,Ovcharenko

, p. 457 - 463 (2006)

The molecular and crystal structures of porphyrexides, viz., 4-amino-2-imino-(1) and (Z)-2-amino-4-bromoimino-5,5-dimethyl-4,5-dihydro-1H- imidazole 1-oxyls (7), and their diamagnetic precursors were determined. Compound 1 is kinetically unstable because it is oxidized with atmospheric oxygen to form (E)-1,2-bis[1-amino-1-(cyanoimino)-2-methyl-propan-2-yl]diazene 1,2-dioxide.
