1-Oxyl-2,2,6,6-tetramethyl-1,2,3,6-tetrahydropyridine-4-carbaldehyde, also known as TEMPO, is a stable nitroxide radical with the chemical formula C10H19NO. It is a versatile organic compound that plays a significant role in various chemical reactions, particularly in oxidation processes. TEMPO is widely used as a catalyst in the oxidation of alcohols to aldehydes or ketones, as well as in the polymerization of various monomers, such as styrene and methyl methacrylate. Its stability and selectivity make it a valuable tool in organic synthesis and industrial applications. Additionally, TEMPO has been studied for its potential use in the treatment of certain diseases, such as malaria, due to its ability to disrupt the cell membranes of parasites.
The CAS Registry Mumber 97188-49-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,1,8 and 8 respectively; the second part has 2 digits, 4 and 9 respectively. Calculate Digit Verification of CAS Registry Number 97188-49: (7*9)+(6*7)+(5*1)+(4*8)+(3*8)+(2*4)+(1*9)=183 183 % 10 = 3 So 97188-49-3 is a valid CAS Registry Number.
