2,2,6,6-Tetramethyl-3-chloro-4-hydroxyiminopiperidine-1-oxide, also known as TEMPO, is a stable, water-soluble, and highly selective nitroxyl radical compound. It is widely used as a catalyst in various chemical reactions, particularly in the oxidation of alcohols to aldehydes or ketones, and in the polymerization of various monomers. TEMPO exhibits unique properties, such as its ability to form stable radicals and its resistance to decomposition, which makes it an ideal catalyst for a range of applications in the chemical industry. Its stability and selectivity also contribute to its use in the synthesis of various organic compounds and in the production of polymers with controlled molecular weights and structures.
The CAS Registry Mumber 85540-95-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,5,4 and 0 respectively; the second part has 2 digits, 9 and 5 respectively. Calculate Digit Verification of CAS Registry Number 85540-95: (7*8)+(6*5)+(5*5)+(4*4)+(3*0)+(2*9)+(1*5)=150 150 % 10 = 0 So 85540-95-0 is a valid CAS Registry Number.
