697-92-7 Usage
General Description
4-Chloro-2,6-dimethylpyridine-N-oxide, also known as DMO, is a chemical compound that is commonly used as a pesticide and insecticide. It is a pyridine derivative with a chlorine atom and two methyl groups attached to the pyridine ring, along with a nitrogen oxide functional group. DMO is known for its high effectiveness in controlling pests and insects, making it widely used in agricultural and horticultural applications. It is often used in the form of a water-soluble liquid or as a component in pesticide formulations. However, it is important to handle this chemical with care due to its potential toxicity to humans and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 697-92-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 697-92:
(5*6)+(4*9)+(3*7)+(2*9)+(1*2)=107
107 % 10 = 7
So 697-92-7 is a valid CAS Registry Number.

C-H Pyridonation of (Hetero-)Arenes by Pyridinium Radical Cations

Pyridones are important heteroaromatic scaffolds found in natural products and pharmaceuticals and are, therefore, of major interest in organic synthetic chemistry. Here we report the first C-H pyridonation of unactivated (hetero-)arenes, providing a methodology to directly access N-aryl-2- and 4-pyridones. Generation of pyridinium radical cations through single-electron reduction allows for the synthesis of pyridones on structurally complex molecules.
