Chemical Properties
Oxydisulfoton is a combustible liquid.
General Description
Liquid. Used as an agricultural insecticide.
Reactivity Profile
Organophosphates, such as DISULFOTON-SULFOXIDE, 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. On heating, oxydisulphoton gets decomposed and releases toxic gases and vapours (SOx, POx).
Health Hazard
DISULFOTON-SULFOXIDE is highly toxic orally and through the skin. DISULFOTON-SULFOXIDE is an organophosphate pesticide.
Fire Hazard
(Non-Specific -- Organophosphorus Pesticide, n.o.s.) Some materials may burn but none of them ignite easily. Container may explode in the heat of fire. When heated to decomposition, DISULFOTON-SULFOXIDE emits very toxic fumes of oxides of sulfur and phosphorus.
Potential Exposure
This material is an agricultural
insecticide.
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Speed in removing material from skin
is of extreme importance. Shampoo hair promptly if contaminated.
Seek medical attention immediately. If this
chemical has been inhaled, remove from exposure, begin
rescue breathing (using universal precautions, including
resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical
attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit. Keep
victim quiet and maintain normal body temperature. Effects
may be delayed; keep victim under observation.
Shipping
UN3018 Organophosphorus pesticides, liquid,
toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Incompatibilities
Vapor may form explosive mixture with
air. Incompatible with oxidizers (chlorates, nitrates, peroxides,
permanganates, perchlorates, chlorine, bromine, fluorine,
etc.); contact may cause fires or explosions. Keep
away from alkaline materials, strong bases, strong acids,
oxoacids, and epoxides. Strong oxidizers may cause release
of toxic phosphorus oxides. Organophosphates, in the presence
of strong reducing agents such as hydrides, may form
highly toxic and flammable phosphine gas. Keep away
from alkaline materials.
Description
Oxydisulfoton is a liquid. Molecularweight = 290.42. Hazard Identification (based on NFPA-704 M Rating System): Health 4, Flammability 1,Reactivity 0.
Waste Disposal
In accordance with 40CFR
165 recommendations for the disposal of pesticides and
pesticide containers. Must be disposed properly by following
package label directions or by contacting your local or
federal environmental control agency, or by contacting
your regional EPA office.
Uses
Disulfoton Sulfoxide is a disulfoton (D493695)'s degradate. Disulfoton, an organophosphate acetylcholinesterase inhibitor, is most commonly used for its pesticidal & insecticidal properties in the agricultural industry.
Definition
ChEBI: Oxydisulfoton is an organic thiophosphate.
Production Methods
The production of disulfoton sulfoxide typically begins with disulfoton, its parent compound. The sulfoxide derivative is synthesised through a controlled oxidation process, where disulfoton is treated with dihydrogen peroxide in the presence of a vanadium-based catalyst, often vanadia, in a solvent like tert-butyl alcohol. This reaction selectively oxidises one of the sulphur atoms to a sulfoxide without over-oxidising to the sulfone. The product is then isolated and purified, usually by solvent extraction and crystallisation, yielding disulfoton sulfoxide with high efficiency.
Mechanism of action
Acetylcholinesterase (AChE) inhibitor
Safety Profile
Poison by ingestion and skin contact. When heated to decomposition it emits very toxic fumes of SOx and POx.
