Molecularweight= 456.56; Boiling point = (decomposes).135℃;Freezing/Melting point = 220℃. Hazard Identification(based on NFPA-704 M Rating System): Health 3,Flammability 1, Reactivity 0. Insoluble in water.
dark amber viscous liquid
Dioxathion is an organophosphate pesticide. It is used as an insecticide on livestock and acaricide on citrus fruits.
ChEBI: Dioxation is a member of dioxanes.
Tan liquid (technical grade is brown). Used for the control of insects and mites on grapes, citrus, walnuts, ornamentals, apples, pears, and quince. Also used as a spray or dip for the control of ticks, lice, hornfly, and sheep ked on cattle, goats, sheep, and hogs.
Insoluble in water. DIOXATHION is stable in water at a neutral pH.
DIOXATHION is heat sensitive. DIOXATHION may react with iron or tin surfaces. DIOXATHION may be hydrolyzed by strong acids or alkalis. . Organophosphates 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.
Very toxic. Probable oral lethal dose for humans is 50-500 mg/kg or between 1 teaspoonful and 1 oz. for a 70 kg (150 lb.) person. It is a cholinesterase inhibitor. Death is primarily due to respiratory arrest arising from failure of the respiratory center, paralysis of respiratory muscles, intense bronchoconstriction, or all three.
Shock can shatter container, releasing contents. (Non-Specific -- Organophosphorus Pesticide, Liquid, n.o.s.) Container may explode in heat of fire. Fire may produce irritating or poisonous gases. Runoff from fire control water may give off poisonous gases. Runoff from fire control or dilution water may cause pollution. When heated to decomposition, DIOXATHION emits highly toxic fumes of oxides of nitrogen, phosphorus, and sulfur. Avoid alkali materials and heat. DIOXATHION is unstable to iron or tin surfaces and when mixed with certain carriers.
Poison by ingestion,
inhalation, skin contact, and intraperitoneal
routes. Mutation data reported. A
cholinesterase inhibitor. When heated to
decomposition it emits very toxic fumes of
POx, and SOx,. See also PARATHION

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Speed in removing material from skinis of extreme importance. Shampoo hair promptly if contaminated. Seek medical attention immediately. If thischemical has been inhaled, remove from exposure, beginrescue breathing (using universal precautions, includingresuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.Effects may be delayed; medical observation is recommended.

Dioxathion requires a “POISONOUS/TOXICMATERIALS” label. They fall in Hazard Class 6.1 and inPacking Group II. This chemical is a regulated marinepollutant.
Incompatible with strong acids.Decomposes above 135℃, forming toxic oxides of phosphorus and sulfur. Attacks iron and tin surfaces.Hydrolyzed by alkalies. Dioxathion is hydrolyzed by strongbases; attacks iron and tin surfaces. Strong oxidizers maycause release of toxic phosphorus oxides.Organophosphates, in the presence of strong reducingagents such as hydrides, may form highly toxic and flammable phosphine gas. Keep away from alkaline materials.
