The Uses of 1,4-Dichlorobutane

Used in organic synthesis including adiponitrile. It is also used as an active pharmaceutical intermediate. 1,4-dichlorobutane (1,4-DCB) can be used as an organic solvent (O) for ion-transfer voltammetry at water (W) interface.

General Description

Colorless mobile liquid with a mild pleasant odor.

Air & Water Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

Halogenated aliphatic compounds, such as 1,4-Dichlorobutane, are moderately or very reactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Materials in this group may be incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. 1,4-Dichlorobutane can react vigorously with oxidizing materials.

Health Hazard

ACUTE/CHRONIC HAZARDS: Irritant.
