white to tan crystals | [Uses]
Pyridine Hydrochloride is the hydrochloride salt of pyridine, a basic six-membered heterocyclic ring. Pyridine is a base structure present in many biologically active compounds like the vitamins niaci
n and pyridoxal. Pyridine is used in dehalogenation reactions and can be used as a base in condensation reactions. | [Preparation]
Pyridine hydrochloride could be synthesized through the liquid-liquid synthesis method (pyridine and hydrochloric acid) and the gas-liquid synthesis method (pyridine and hydrogen chloride gas) respectively. The yield of the liquid-liquid synthesis method was 85% and the gas-liquid synthesis method was 92%.
| [Purification Methods]
Crystallise the salt from CHCl3/EtOAc and wash it with Et2O. It is hygroscopic.[Beilstein 20 H 185, 20 I 57, 20 II 103, 20 III/IV 2230, 20/5 V 180.] |
