2-Chloropyridine Usage And Synthesis

Chemical Properties

Clear colourless to light yellow liquid

Uses

2- Chloropyridine is used as an intermediate chemical in the production of various pyrithione, for use in cosmetics, personal care products and pharmaceutical products.

Uses

2-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.

Definition

ChEBI: 2-chloropyridine is a monochloropyridine.

General Description

A colorless oily liquid. Toxic by ingestion and/or skin absorption. Used to make other chemicals.

Air & Water Reactions

Slightly soluble in water and denser than water.

Hazard

Toxic by ingestion.

Fire Hazard

Combustible 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 Profile

Poison 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 Methods

Dry 2-chloropyridine with NaOH for several days, then distil it from CaO under reduced pressure. [Beilstein 20/5 V 402.]
