Thionazin (297-97-2)
Hazard InformationBack Directory
[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.
[Definition]

ChEBI: Thionazin is an organic thiophosphate.
[Production Methods]

Thionazin is commercially synthesised by esterifying pyrazin-2-ol with O,O-diethyl phosphorothioic acid chloride. The production process begins with the preparation of pyrazin-2-ol, which is reacted with O,O-diethyl phosphorothioic acid chloride under controlled conditions to form the active ester: O,O-diethyl O-(pyrazin-2-yl) phosphorothioate. This reaction typically occurs in an organic solvent like toluene or chloroform, using a base such as pyridine to neutralise the hydrochloric acid by-product.
[Mechanism of action]

Acetylcholinesterase (AchE) inhibitor.
[Pesticide Type]

Nematicide; Insecticide
