Carbophenothion is an off-whiteto light-amber-coloured liquid with a mild mercaptanlike
odour. It is slightly soluble in water and miscible with many organic solvents such
as hydrocarbons, alcohols, ketones, and esters. The U.S. EPA has grouped it under RUP.
Carbophenothion is used as a non-systemic insecticide and acaricide used for preharvest
treatments on deciduous, citrus and small fruits, field crops, and vegetables and for
the control of aphids, mites, suckers, and other pests on fruit, nuts, vegetables, sorghum,
and maize.

Carbophenothion is a colorless to light amber
liquid with a characteristic odor.
Nonsystemic insecticide and acaricide for controlling mites, aphids and other insects
on deciduous fruit trees.
Carbophenothion is an organophosphorus pesticide used for fruits and vegetables.
ChEBI: Carbophenothion is an organic sulfide.
Carbophenothion is commercially produced by synthesising the compound S-(4-chlorophenylthiomethyl) O,O-diethyl phosphorodithioate, which likely required the reaction of 4-chlorobenzyl mercaptan with diethyl phosphorochloridothioate or similar phosphorus-containing intermediates. The process would have included steps such as chlorination, thiolation, and esterification, carried out under controlled conditions to ensure purity and stability.
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.
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.
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.
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
Highly toxic cholinesterase inhibitor; exhibitsacute, delayed, and chronic poisoning; expo-sure risk of inhalation of vapors, however,may be low because of its very low vaporpressure [3.0 *10 -7 torr at 20 °C (68 °F)];also, severity of toxicity may vary widelyfrom species to species; rats are more vul-nerable to its effect than are mice or rabbits;signs of toxicity in human include headache,dizziness, muscle spasms, tearing, blurredvision, salivation, vomiting, abdominal pain,diarrhea, chest pain, and convulsions; highexposure can cause coma and death; inges-tion of 0.4–1 g can be lethal to adult humans.
LD50 oral (rat): in the range 7–10 mg/kg
LD50 skin (rat): 27 mg/kg.
(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.
Contact and stomach action with long residual activity. Acetylcholinesterase (AchE) inhibitor.
Poison by ingestion,
skin contact, and intraperitoneal routes.
Moderately toxic by subcutaneous route.
Mutation data reported. A cholinesterase
inhibitor. When heated to decomposition it
emits very toxic fumes of SOx, POx, and Cl-.

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Speed in removing material from skinis of extreme importance. Shampoo hair promptly if contaminated. Seek medical attention immediately. If thischemical has been inhaled, remove from exposure, beginrescue breathing (using universal precautions, includingresuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit
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).

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.
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.
