2,6-Dimethoxyphenyl-t-butyl-nitroxid-Radikal, also known as 2,6-dimethoxyphenyl-t-butyl nitrone or DMPO, is a stable nitroxide radical commonly used as a spin trapping agent in electron paramagnetic resonance (EPR) spectroscopy. It is a colorless, crystalline solid with the molecular formula C11H17NO3. DMPO is widely employed in the study of free radicals and reactive oxygen species in various chemical, biological, and medical applications. The compound's structure features a 2,6-dimethoxyphenyl group attached to a t-butyl group, with a nitrone functional group that can trap free radicals, forming stable radical adducts. These adducts can then be analyzed using EPR, providing valuable information about the nature and concentration of radicals present in a given system. DMPO's stability, solubility, and reactivity make it a popular choice for studying radical reactions and processes in both in vitro and in vivo settings.
The CAS Registry Mumber 3416-29-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,1 and 6 respectively; the second part has 2 digits, 2 and 9 respectively. Calculate Digit Verification of CAS Registry Number 3416-29: (6*3)+(5*4)+(4*1)+(3*6)+(2*2)+(1*9)=73 73 % 10 = 3 So 3416-29-3 is a valid CAS Registry Number.
