THIONAZIN Chemical Properties,Uses,Production
Chemical Properties
Amber liquid. Slightly soluble in water; miscible with most organic solvents.
Uses
Nematocide; insecticide.
General Description
Amber liquid. Pure compound is almost colorless; technical product is light brown to tan. Used in insecticides, fungicides, and nematocides. Not registered as a pesticide in the U.S.
Reactivity Profile
Organothiophosphates, such as THIONAZIN, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
Hazard
Toxic by ingestion, inhalation, and skin absorption; cholinesterase inhibitor.
Health Hazard
Cholinesterase inhibitor. (Non-Specific -- Organic Phosphate Compound, Liquid, Poison B). Poisonous; may be fatal if inhaled, swallowed or absorbed through skin. Contact may cause burns to skin and eyes.
Fire Hazard
(Non-Specific -- Organic Phosphate Compound, Liquid, Poison B). THIONAZIN may burn but does not ignite readily. (Non-Specific -- Organic Phosphate Compound, Liquid, Poison B). Fire may produce irritating or poisonous gases.
Safety Profile
Poison by ingestion, skin contact, and ocular routes. A cholinesterase inhibitor type of insecticide. When heated to decomposition it emits highly toxic fumes of NOx, POx, and SOx. See also PARATHION.
