2-(2-chloro-4-nitrophenyl)pyridine is an organic compound characterized by its molecular formula C11H6ClN3O2. 2-(2-chloro-4-nitrophenyl)pyridine features a pyridine ring, which is a six-membered aromatic ring containing one nitrogen atom, and a 2-chloro-4-nitrophenyl group attached to it. The 2-chloro-4-nitrophenyl moiety consists of a benzene ring with a chlorine atom at the 2nd position and a nitro group (-NO2) at the 4th position. The presence of both electron-withdrawing nitro group and electron-donating chloro group in the molecule can influence its reactivity and properties. This chemical is primarily used in the synthesis of various pharmaceuticals and agrochemicals due to its potential to form different types of chemical bonds and its ability to act as a building block for more complex molecules.

4420-82-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4420-82-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,2 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4420-82:
(6*4)+(5*4)+(4*2)+(3*0)+(2*8)+(1*2)=70
70 % 10 = 0
So 4420-82-0 is a valid CAS Registry Number.

Silver-catalyzed arylation of (hetero)arenes by oxidative decarboxylation of aromatic carboxylic acids

Kan, Jian,Huang, Shijun,Lin, Jin,Zhang, Min,Su, Weiping

supporting information, p. 2199 - 2203 (2015/02/19)

A long-standing challenge in Minisci reactions is achieving the arylation of heteroarenes by oxidative decarboxylation of aromatic carboxylic acids. To address this challenge, the silver-catalyzed intermolecular Minisci reaction of aromatic carboxylic acids was developed. With an inexpensive silver salt as a catalyst, this new reaction enables a variety of aromatic carboxylic acids to undergo decarboxylative coupling with electron-deficient arenes or heteroarenes regardless of the position of the substituents on the aromatic carboxylic acid, thus eliminating the need for ortho-substituted aromatic carboxylic acids, which were a limitation of previously reported methods.

This invention relates to agents that are inhibitors or activators of variant forms of endogenous proteins and novel methods of identifying such variants. Of particular interest are inhibitors and activators of endogenous protein variants, encoded by genes which have mutated, which variants often arise or are at least first identified as having arisen following exposure to a chemical agent which is known to be an inhibitor or activator of the corresponding unmutated endogenous protein.
