The Uses of TECNAZENE
1,2,4,5-Tetrachloro-3-nitrobenzene, is a metabolite of pentachloronitrobenzene (P237990), used as fungicide, and pesticide.
What are the applications of Application
1,2,4,5-Tetrachloro-3-nitrobenzene is a fungicide
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A C-nitro compound that is nitrobenzene in which the four hydrogens located ortho- and para- to the nitro group have been replaced by chlorines.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.]
