| | Pentachloropyridine Usage And Synthesis |
| Description | Pentachloropyridine 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.
