Chemical Properties
Carbophenothion is an off-white to light amber colored liquid with a mild mercaptanlike odor. It is slightly soluble in water, and miscible with many organic solvents, such
as hydrocarbons, alcohols, ketones, and esters. The US EPA has classifi ed it as an RUP.
Carbophenothion is used as a non-systemic insecticide and acaricide for pre-harvest
treatments on deciduous, citrus and small fruits, fi eld crops, and vegetables, and for the
control of aphids, mites, suckers, and other pests on fruit, nuts, vegetables, sorghum,
and maize
General Description
An off-white to amber liquid with a mild odor of rotten eggs. Used as an insecticide and acaricide, primarily for citrus crops and deciduous fruits and nuts.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
CARBOPHENOTHION is a halogenated organophosphate derivative. Organophosphates 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
CARBOPHENOTHION is highly toxic; the estimated fatal oral dose is 0.6 g for a 150 lb. (70 kg) person. It is an indirect cholinesterase inhibitor, meaning its effects are on the nervous system.
Fire Hazard
(Non-Specific -Organophosphorus Pesticide Liquid, n.o.s.) Container may explode in heat of fire. Fire and runoff from fire control water may produce irritating or poisonous gases.
Health Hazard
Carbophenothion is highly toxic through ingestion and skin absorption.
Carbophenothion affects the nervous system by inhibiting ChE activity. On heating or
burning, carbophenothion undergoes decomposition and produces toxic fumes such
as phosphorus oxides, sulfur oxides, and hydrogen chloride. Exposures to carbophenothion cause poisoning with symptoms such as headache, blurred vision, weakness,
nausea, discomfort in the chest, abdominal cramps, vomiting, diarrhea, salivation,
sweating, and pinpoint pupils. It is highly toxic when eaten and nearly as toxic when
absorbed through the skin. Large single doses of carbophenothion potentiate the
toxicity of malathion
Potential Exposure
Those engaged in the manufacture or
application of this material, which is an insecticide and
acaricide; primarily for citrus crops and deciduous fruits
and nuts.
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.
Shipping
UN3018 Organophosphorus pesticides, liquid,
toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
UN 2783 Organophosphorus pesticides, solid, toxic, Hazard
Class: 6.1; Labels: 6.1-Poisonous material.
Incompatibilities
The substance decomposes on heating or
on burning, producing toxic fumes including phosphorus
oxides, sulfur oxides, hydrogen chloride. 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
Hydrolysis by hypochlorites
may be used, as may incineration, 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 contactingyour local or federal environmental control agency, or by
contacting your regional EPA office.
Uses
Carbophenothion is an organophosphorus pesticide used for fruits and vegetables.
Uses
Miticide; insecticide.
Uses
Nonsystemic insecticide and acaricide for controlling mites, aphids and other insects
on deciduous fruit trees.
Definition
ChEBI: Carbophenothion is an organic sulfide.
Environmental Fate
Soil. Though no products were reported, the half-life was reported to be ≥100 days
(Verschueren, 1983).
Chemical/Physical. Oxidizes to sulfoxide, sulfone, thiol, thiosulfone and thiosulfoxide
(Hartley and Kidd, 1987). Emits toxic fumes of chlorine, phosphorus and sulfur oxides
when heated to decomposition (Sax and Lewis, 1987).
storage
