Usage

Description

THIONAZIN is a chemical compound with the appearance of an amber liquid. The pure compound is almost colorless, while the technical product is light brown to tan. It is characterized by its slightly soluble nature in water and miscibility with most organic solvents.

Uses

Used in Pesticide Industry:
THIONAZIN is used as a nematocide for controlling nematodes, which are microscopic worms that can cause significant damage to crops. It is also employed as an insecticide to protect plants from harmful insects and as a fungicide to prevent the growth of fungi that can harm crops.
Used in Nematocide Applications:
THIONAZIN is used as a nematocide for [application reason], which is to control and eliminate nematodes that can cause damage to crops and affect agricultural productivity.
Used in Insecticide Applications:
THIONAZIN is used as an insecticide for [application reason], which is to protect plants from harmful insects that can cause damage to crops and reduce their yield.
Used in Fungicide Applications:
THIONAZIN is used as a fungicide for [application reason], which is to prevent the growth of fungi that can harm crops and affect their overall health and productivity.
Please note that THIONAZIN is 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

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.

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.
