2-Chloropyridine Usage And Synthesis
Chemical PropertiesClear colourless to light yellow liquid
Uses2- Chloropyridine is used as an intermediate chemical in the production of various pyrithione, for use in cosmetics, personal care products and pharmaceutical products.
Uses2-Chloropyridine (2-CPY) has been identified as a trace organic chemical in process streams, wastewater and even drinking water. Furthermore, it appears to be formed as a secondary pollutant during t he decomposition of specific insecticides.
DefinitionChEBI: 2-chloropyridine is a monochloropyridine.
Synthesis Reference(s)Synthetic Communications, 19, p. 897, 1989 DOI: 10.1080/00397918908051009
Synthesis, p. 337, 1990
General DescriptionA colorless oily liquid. Toxic by ingestion and/or skin absorption. Used to make other chemicals.
Air & Water ReactionsSlightly soluble in water and denser than water.
HazardToxic by ingestion.
Fire HazardCombustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
Safety ProfilePoison by ingestion, inhalation, skin contact, and intraperitoneal routes. Combustible when exposed to heat or flame. Can react with oxidizing materials. When heated to decomposition it emits very toxic fumes of Cl-, NOx, and phosgene.
Purification MethodsDry 2-chloropyridine with NaOH for several days, then distil it from CaO under reduced pressure. [Beilstein 20/5 V 402.]
