Raw materials And Preparation Products

Hazard Information

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.

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.
