| | DIALIFOS Usage And Synthesis |
| Chemical Properties | Dialifor is a crystalline solid. The commercial
product may also be available as a colorless oil. | | Uses | Insecticide; acaricide. | | Uses | Nonsystemic insecticide and acaricide to control chewing and sucking insects and
spider mites on a wide variety of fruits and vegetables. | | Definition | ChEBI: Dialifor is a member of isoindoles. | | General Description | White crystalline solid, also reported as a colorless oil, colorless. Used as an insecticide and acaricide (kills beetles, ticks, mites, etc.). | | Reactivity Profile | Releases nitrogen oxides, sulfur oxides, and phosphorus oxides when heated. Readily hydrolyzed by concentrated alkali. Avoid alkali. [EPA, 1998]. Organophosphates, such as DIALIFOS, 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. | | Health Hazard | DIALIFOS can cause serious symptoms and in extreme cases death by respiratory arrest. | | Health Hazard | Highly toxic by all routes of exposure;exhibits acute, delayed, and chronic effect;cholinesterase inhibitor; symptoms of poi-soning are similar to those of parathion,including weakness and twitching of mus-cle, headache, giddiness, dizziness, excessivesalivation, lacrimation, tightness in chest,blurred vision, slurred speech, mental confu-sion, and drowsiness; gastrointestinal effectsinclude nausea, vomiting, stomach cramps,and diarrhea; heavy exposure can lead to dif-ficulty in breathing, convulsions, and coma;median lethal doses reported in the literatureshow inconsistent and varying values.
LD50 oral (rat): 5–53 mg/kg
LD50 oral (mouse): 39–65 mg/kg
LD50 oral (rabbit): 35 mg/kg
LD50 skin (rabbit): 145 mg/kg. | | Fire Hazard | Releases nitrogen oxides, sulfur oxides, and phosphorus oxides when heated. Readily hydrolyzed by concentrated alkali. Avoid alkali. | | Safety Profile | Poison by ingestion and
skin contact. An experimental teratogen.
Other experimental reproductive effects.
When heated to decomposition it emits
toxic fumes of SOx, POx, and NOx. | | Potential Exposure | A potential danger to those involved
in the manufacture, formulation and application of this
insecticide. | | Environmental Fate | Chemical/Physical. Though no products were identified, the hydrolysis half-lives at
20°C were 15 days and 14 hours at pH 6.1 and pH 7.4, respectively (Freed et al., 1979,
1979a). | | Shipping | UN2811 Toxic solids, organic, n.o.s., Hazard
Class: 6.1; Labels: 6.1-Poisonous materials, Technical
Name Required. | | Incompatibilities | Strong bases. Contact with oxidizers
may cause the release of phosphorous oxides. Contact with
strong reducing agents, such as hydrides, may cause the
formation of flammable and toxic phosphine gas. | | Waste Disposal | Alkaline hydrolysis or
incineration. In accordance with 40CFR165, follow recom-
mendations for the disposal of pesticides and pesticide
containers. Must be disposed properly by following pack-
age label directions or by contacting your local or federal
environmental control agency, or by contacting your
regional EPA office. |
