Usage

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

Different sources of media describe the Health Hazard of 297-97-2 differently. You can refer to the following data:
1. Extremely toxic by ingestion and skinabsorption; cholinesterase inhibitor; exhibitsacute, delayed, and chronic effect; symptomsof cholinergic effects include excessive salivation, lacrimation, blurred vision, musclespasms, headache, weakness, mental confusion, vomiting, diarrhea, stomach pain, convulsions, and coma; also causes shortnessof breath, respiratory depression, and respiratory paralysis; ingestion of small quantity(0.5–1.59) could be fatal to adult humans;poisoning effects may onset several hoursafter exposure.LD50 oral (rat): 3.5–6 mg/kgLD50 oral (mouse): 5 mg/kgLD50 skin (rat): 8 mg/kgLD50 skin (guinea pig): 10 mg/kg.
2. 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.
