α,α-di(4-methylphenyl)-N-phenyl nitrone, also known as 4-Oxo-TEMPO, is a stable nitroxide radical with the chemical formula C20H19NO. It is a derivative of the nitrone family, characterized by the presence of a nitrone functional group (C=N-O) and two 4-methylphenyl groups attached to the alpha carbon. α,α-di(4-methylphenyl)-N-phenyl nitrone is widely used as a spin label and a free radical scavenger in various applications, including electron paramagnetic resonance (EPR) spectroscopy, polymerization reactions, and as an antioxidant in organic synthesis. Its stability and reactivity make it a valuable tool in studying the behavior of free radicals and understanding the mechanisms of various chemical processes.

29127-91-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 29127-91-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,1,2 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.Calculate Digit Verification of CAS Registry Number 29127-91:
(7*2)+(6*9)+(5*1)+(4*2)+(3*7)+(2*9)+(1*1)=121
121 % 10 = 1
So 29127-91-1 is a valid CAS Registry Number.
