115-90-2 Usage
Uses
Used in Agriculture:
Fensulfothion is used as an insecticide and nematocide for controlling various pests, including free-living, cyst-forming, and root-knot nematodes, as well as soil insects in vegetable and fruit crops. Its application helps protect crops from damage and increases agricultural productivity.
Used in Nematode Control:
Fensulfothion is employed as a nematocide to control nematodes that can cause significant damage to crops. By targeting these harmful organisms, it helps maintain the health of the plants and contributes to better crop yields.
Used in Insect Control:
As an insecticide, Fensulfothion is used to control a wide range of insects that can harm crops and plants. Its effectiveness in controlling these pests helps to protect the agricultural industry from potential losses.
Used in Mosquito Larviciding:
Fensulfothion is also used as a mosquito larvicide, targeting the larval stages of mosquitoes to prevent their development into adult mosquitoes. This application helps in controlling mosquito populations and reducing the spread of mosquito-borne diseases.
Air & Water Reactions
Incompatible with alkali chemicals. Hydrolyzes in alkali, isomerize in air [EPA, 1998]. Slightly soluble in water.
Reactivity Profile
Organothiophosphates, such as FENSULFOTHION, 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
Cholinesterase inhibitor. Questionable carcinogen.
Health Hazard
FENSULFOTHION displays cholinesterase inhibiting properties. Death results primarily from respiratory arrest stemming from failure of the respiratory center, paralysis of respiratory muscles and intense bronchoconstriction.
Fire Hazard
(Non-Specific -- Organophosphorus Pesticide, Liquid, n.o.s.) FENSULFOTHION may burn but may not ignite readily. Containers may explode in heat of fire. When heated highly toxic fumes of phosphorus and sulfur oxides are emitted. Incompatible with alkali chemicals. Hydrolyzes in alkali, isomerizes in air.
Safety Profile
A poison by ingestion,
inhalation, and skin contact. Experimental
reproductive effects. A pesticide. When
heated to decomposition it emits very toxic
fumes of SOx and POx.
Potential Exposure
A potential danger to those involved
in the manufacture, formulation, or application of this
insecticide used to control parasitic, sedentary, and freeliving nematodes.
Environmental Fate
Soil. In soils, the bacterium Klebsiella pneumoniae degraded fensulfothion to fensulfothion sul?de (Timms and MacRae, 1982, 1983). The following microorganisms were also capable of degrading the parent compound to the corresponding sul?de: Escherichia coli, Pseudomonas ?uorescens, Nocardia opaca, Lactobacillus plantarum and Leuconostoc mesenteroides (Timms and MacRae, 1983).Plant. Readily oxidized in plants to the corresponding sulfone (Hartley and Kidd, 1987).Chemical/Physical. Emits toxic fumes of phosphorus and sulfur oxides when heated to decomposition (Sax and Lewis, 1987; Lewis, 1990).Isomerizes readily to the O,S-diethyl isomer (Worthing and Hance, 1991). The hydrolysis half-lives of fensulfothion in a sterile 1% ethanol/water solution at 25°C and pH values of 4.5, 6.0, 7.0 and 8.0, were 69, 77, 87 and 58 weeks, respectively (Chapman and Cole, 1982).
Shipping
UN3018 Organophosphorus pesticides, liquid,

Labels: 6.1-Poisonous materials, Technical Name Required
Incompatibilities
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, 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.
Waste Disposal
Alkaline hydrolysis. In
accordance with 40CFR165, follow 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.
Check Digit Verification of cas no
The CAS Registry Mumber 115-90-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 115-90:
(5*1)+(4*1)+(3*5)+(2*9)+(1*0)=42
42 % 10 = 2
So 115-90-2 is a valid CAS Registry Number.
