2-Methyl-3-nitropyridine N-oxide is an organic compound with the chemical formula C6H6N2O3. It is a derivative of pyridine, a heterocyclic aromatic compound, and features a methyl group at the 2nd position and a nitro group at the 3rd position. The N-oxide functional group is attached to the nitrogen atom in the pyridine ring, which can influence the compound's reactivity and properties. 2-Methyl-3-nitropyridine N-oxide is often used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals due to its unique structure and reactivity. It is typically synthesized through oxidation of 2-methyl-3-nitropyridine using an oxidizing agent such as hydrogen peroxide or m-chloroperoxybenzoic acid. The compound is a yellow solid and is sensitive to light and heat, requiring proper storage conditions to maintain its stability.

Check Digit Verification of cas no

The CAS Registry Mumber 5236-76-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,3 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5236-76:
(6*5)+(5*2)+(4*3)+(3*6)+(2*7)+(1*6)=90
90 % 10 = 0
So 5236-76-0 is a valid CAS Registry Number.

Facile one-pot direct arylation and alkylation of nitropyridine N -oxides with grignard reagents

Zhang, Fang,Duan, Xin-Fang

supporting information; experimental part, p. 6102 - 6105 (2012/01/06)

Facile arylation and alkylation of nitropyridine N-oxides were developed through the reactions of Grignard reagents with nitropyridine N-oxides. For the same 4-nitropyridine N-oxide, arylation occurred at the 2- (or 6-) position, whereas alkylation occurred at the 3-position in an adjustably site-selective manner. The cooperative action of the two groups was discovered in the reactions of 3-nitropyridine N-oxides. This protocol can find wide applications in building various pyridine compounds as illustrated in total syntheses of Emoxipin and Caerulomycin A and E.

OXIDATIVE DEMETHYLATION OF SOME METHYLNITROPYRIDINE 1-OXIDES

Achremowicz, Lucjan

, p. 2433 - 2434 (2007/10/02)

3-Nitropyridine 1-oxide and 5-methyl-3-nitropyridine 1-oxide are produced readily by oxidative demethylation using SeO2 of 2-methyl- and 2,5-dimethyl-3-nitropyridine 1-oxides.
