139-83-3 Usage

General Description

3,5-Dibutylpyridine is a chemical compound with the molecular formula C14H21N. It is a pyridine derivative with two butyl groups attached to the 3 and 5 positions of the pyridine ring. 3,5-Dibutylpyridine is commonly used as a ligand in coordination chemistry and as a catalyst in organic synthesis reactions. It has a high boiling point and is insoluble in water, but soluble in organic solvents. 3,5-Dibutylpyridine is also used as an intermediate in the production of pharmaceuticals, agrochemicals, and other specialty chemicals. Its properties make it a valuable component in various industrial applications.

Check Digit Verification of cas no

The CAS Registry Mumber 139-83-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139-83:
(5*1)+(4*3)+(3*9)+(2*8)+(1*3)=63
63 % 10 = 3
So 139-83-3 is a valid CAS Registry Number.

An Improved Liquid-Phase Synthesis of Simle Alkylpyridines

Grayson, J. Ian,Dinkel, Rolf

, p. 2100 - 2110 (2007/10/02)

The synthesis of pyridines from mixtures of aldehydes or ketones and NH3 in the liquid phase has been reinvestigated, using continuous dosage of the carbonyl components to the reaction mixture.The main product from the reaction of acetaldehyde and formaldehyde is 3-methylpyridine (6), which is also the main product from the reaction of acrolein or a mixture of crotonaldehyde and formaldehyde under the same conditions.The reaction of other aldehydes with formaldehyde give 3,5-dialkylpyridines, e.g. 10, 16.Acetone reacts with either formaldehyde or acetaldehyde to give polysubstituted alkylpyridines.A mechanistic pathway is proposed which accounts for the formation of the observed products.
