Pyridine, 3-(phenylazo)-, 1-oxide, also known as 3-(phenylazo)pyridine 1-oxide or C12H10N3O, is an organic compound characterized by a pyridine ring with a phenylazo group attached at the 3-position and an oxide group at the 1-position. This nitrogen-containing heterocyclic compound is often used as a building block in the synthesis of various dyes, pigments, and pharmaceuticals due to its unique chemical properties. It is typically synthesized through diazotization and coupling reactions, and its structure and reactivity make it a valuable intermediate in organic chemistry.

2569-65-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2569-65-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,6 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2569-65:
(6*2)+(5*5)+(4*6)+(3*9)+(2*6)+(1*5)=105
105 % 10 = 5
So 2569-65-5 is a valid CAS Registry Number.

THERMAL AND PHOTOCHEMICAL DECOMPOSITION OF 3- AND 4-AZIDOPYRIDINE 1-OXIDES IN NUCLEOPHILIC SOLVENTS

Abramovitch, Rudolph A.,Bachowska, Barbara,Tomasik, Piotr

, p. 805 - 815 (2007/10/02)

The thermolysis and photolysis of the title compounds in aniline, N-methylaniline, N,N-dimethylaniline, morpholine and dioxane containing methoxide ion in methanol afforded complex mixtures from which only major products were isolated.No ring-expansion products were detected.In aniline, many of its known oxidation products were found, the N-oxide acting as an oxidizing agent.Hydrogen-abstraction products were the main ones formed from pyridine 1-oxides.
