N-(1,2,2,6,6-pentamethyl-4-piperidylidene)hydroxylamine, also known as 4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl (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 oxidation processes. TEMPO exhibits unique properties, such as its ability to form stable radicals and its resistance to decomposition, which makes it an ideal candidate for applications in organic synthesis, polymer chemistry, and materials science. Additionally, it has been employed as a spin label in electron paramagnetic resonance (EPR) spectroscopy to study the dynamics of biomolecules and as an antioxidant in food preservation. The versatility and stability of TEMPO make it a valuable tool in the field of chemistry.

6636-23-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6636-23-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,3 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6636-23:
(6*6)+(5*6)+(4*3)+(3*6)+(2*2)+(1*3)=103
103 % 10 = 3
So 6636-23-3 is a valid CAS Registry Number.
