| Hazard Information | Back Directory | [General Description]
Straw colored liquid. Used as a pesticide. | [Reactivity Profile]
Organophosphates, such as PIRIMIFOS-ETHYL, 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]
Pirimifos-ethyl is an organophosphorus pesticide and is absorbed by the skin, as well as by the respiratory and gastrointestinal tracts. It is a cholinesterase inhibitor, acting on the nervous system. | [Potential Exposure]
A potential danger to those involved in the manufacture, formulation and application of this organophosphate soil insecticide. | [Fire Hazard]
As with other organophosphorus pesticides, container may explode in heat of fire. Heat may cause decomposition and evolution of highly toxic fumes of phosphorus oxides, nitrogen oxides and sulfur oxides. Decomposes above 266F. | [First aid]
UN3278 Organophosphorus compound, liquid, toxic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required, Potential Inhalation Hazard (Special Provision 5). | [Shipping]
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. | [Incompatibilities]
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 oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately 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 themselves. Medical observation is recommended for 2448 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. | [Chemical Properties]
Pirimifos-ethyl is a straw-colored liquid | [Uses]
Pirimiphos Ethyl is a pesticide used in the protection of crops. Insecticide. | [Definition]
ChEBI: Pirimiphos-ethyl is an organic thiophosphate. | [Production Methods]
The industrial synthesis of pirimiphos-ethyl begins with the preparation of the pyrimidine ring, typically formed via condensation of acetylacetone with guanidine or its derivatives to yield 2-diethylamino-6-methylpyrimidin-4-ol. This intermediate is then reacted with diethyl phosphorochloridothioate in the presence of a base such as triethylamine to form the phosphorothioate ester linkage. The reaction is carried out in organic solvents like toluene or acetonitrile under controlled temperature and pH conditions to ensure high yield and purity. | [Mechanism of action]
Broad-spectrum with contact and respiratory action. Acetylcholinesterase (AchE) inhibitor. | [Pesticide Type]
Insecticide; Acaricide |
