TECNAZENE Usage And Synthesis

Chemical Properties

beige fine crystalline powder

Uses

1,2,4,5-Tetrachloro-3-nitrobenzene, is a metabolite of pentachloronitrobenzene (P237990), used as fungicide, and pesticide.

Definition

ChEBI: A C-nitro compound that is nitrobenzene in which the four hydrogens located ortho- and para- to the nitro group have been replaced by chlorines. A fungicide used to control dry rot, it is no longer approved for se within the European Union.

General Description

Pale yellow crystals.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

TECNAZENE will behave as a weak oxidizer, and will react with strong reducing agents including hydrides, sulfides and nitrides.

Health Hazard

ACUTE/CHRONIC HAZARDS: TECNAZENE may cause irritation on contact. When heated to decomposition it emits toxic fumes.

Fire Hazard

Flash point data for TECNAZENE are not available. TECNAZENE is probably combustible.

Purification Methods

Crystallise it from aqueous EtOH or H2O. [Beilstein 5 III 617, 5 IV 728.]
