Uses
Insecticide; acaricide.
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.
Fire Hazard
Releases nitrogen oxides, sulfur oxides, and phosphorus oxides when heated. Readily hydrolyzed by concentrated alkali. Avoid alkali.
Potential Exposure
A potential danger to those involved
in the manufacture, formulation and application of this
insecticide.
First aid
Move victim to fresh air. Call 911 or emergency
medical service. Give artificial respiration if victim is not
breathing. Do not use mouth-to-mouth method if victim
ingested or inhaled the substance; give artificial respiration
with the aid of a pocket mask equipped with a one-way valve
or other proper respiratory medical device. Administer oxy-
gen if breathing is difficult. Remove and isolate contaminated
clothing and shoes. In case of contact with substance, imme-
diately flush skin or eyes with running water for at least
20 minutes. For minor skin contact, avoid spreading material
on unaffected skin. Keep victim warm and quiet. Effects of
exposure (inhalation, ingestion, or skin contact) to substance
may be delayed. Ensure that medical personnel are aware of
the material(s) involved and take precautions to protect them-
selves. Medical observation is recommended for 24 to
48 hours after breathing overexposure, as pulmonary edema
may be delayed. As first aid for pulmonary edema, a doctor
or authorized paramedic may consider administering a drug
or other inhalation therapy.
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.
Definition
ChEBI: Dialifor is a member of isoindoles.
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).
storage
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with dialiforyou should be trained on its proper handling and storage.Store in tightly closed containers in a cool, well-ventilatedarea away from strong bases.
