| Hazard Information | Back Directory | [Description]
Pentachloropyridine( 2176-62-7) is one of the most important perhalogenated compounds which find broad applications in many fields of chemistry. It is most reactive at the 4- position. Reduction with zinc, or electrochemically, yields 2,3,5,6-tetrachloropyridine. Partial hydrolysis and phosphorylation gives the insecticide chlorpyrifos.
| [Chemical Properties]
WHITE TO OFF-WHITE FLAKES | [Uses]
Pentachloropyridine is a halogenated pyridine with antineoplastic and antiapoptic properties. | [Preparation]
Pentachloropyridine can be produced through a direct electrophilic substitution reaction between pyridine and chlorine. | [Safety Profile]
Poison by intraperitoneal route. When heated to decomposition it emits very toxic fumes of Clí and NOx. | [Purification Methods]
Purify it by recrystallisation from EtOH or aqueous EtOH. It sublimes at 150o/3mm. [den Hertog et al. Recl Trav Chim Pays-Bas 69 673 1950, Schikh et al. Chem Ber 69 2604 1936, Beilstein 20 I 81, 20 III/IV 2503, 20/5 V 422.] |
