2,3,4,7,8-Pentachlorodibenzofuran Chemical Properties,Uses,Production

Uses

2,3,4,7,8-Pentachlorodibenzofuran, is a toxic polychlorinated dibenzofurans (PCDD/F), detected in domestic meat and poultry. It can be used as purified standards for analytical, toxic, and biological studies of these environmental contaminants.

Definition

ChEBI: 2,3,4,7,8-Pentachlorodibenzofuran is a polychlorinated dibenzofuran.

General Description

Solid.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Simple aromatic halogenated organic compounds are very unreactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.

Health Hazard

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

Flash point data for 2,3,4,7,8-PENTACHLORODIBENZOFURAN are not available. 2,3,4,7,8-PENTACHLORODIBENZOFURAN is probably combustible.
