Pyridine(110-86-1) is a polar, basic, low-reactive solvent, especially for dehydrochlorination reactions and extraction of antibiotics. In elimination reaction, pyridine acts as the base of the elimination reaction and bonds the resulting hydrogen halide to form a pyridinium salt. In esterification...

Pyridine being a base, is used to remove th side product i.e. HCl from reaction mixture.
On cooling, crystals of pyridine-HgCl2 (1:1) complex separated and were filtered off, crystallised from 1% HCl (to m 178.5-179o), washed with a little EtOH and dried at 110o. The free base was liberated by addition of excess aqueous NaOH and separated by steam distillation. The ...
“HCl” in a structural formula indicates that the compound is a monohydrochloride, “2HCl” indicates that the compound is a dihydrochloride, and “3HCl” indicates that the compound is a trihydrochloride. A double bond represented with two crossed lines in a chemical formula indicates that the ...
11 ml of HCl in dioxane (4 molar) is added. The mixture is stirred 3 h at room temperature. The mixture is filtered and the solid washed with dioxane. The product is purified by chromatography; HPLC/MS: 1.02 min, [M+H]=376; 1H NMR (400 MHz, DMSO-d6)δ [ppm] 9.08 (d, J=2....
