786-19-6 Usage
Description
Carbophenothion is an off-white to light-amber colored liquid with a mild mercaptan-like odor. 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.
Used in Agriculture:
Carbophenothion is used as a non-systemic insecticide and acaricide for preharvest treatments on deciduous, citrus, and small fruits, field crops, and vegetables. It is effective in controlling pests such as aphids, mites, suckers, and other insects on fruit, nuts, vegetables, sorghum, and maize.
Used in Fruit Trees:
Carbophenothion is used as a miticide and insecticide for controlling mites, aphids, and other insects on deciduous fruit trees.
Used in Fruits and Vegetables:
Carbophenothion is an organophosphorus pesticide used for the protection and treatment of fruits and vegetables against various pests.
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.
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
Health Hazard
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/kgLD50 skin (rat): 27 mg/kg.
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.
Safety Profile
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-.

MERCAPTANS.
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.
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).
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.
Check Digit Verification of cas no
The CAS Registry Mumber 786-19-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,8 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 786-19:
(5*7)+(4*8)+(3*6)+(2*1)+(1*9)=96
96 % 10 = 6
So 786-19-6 is a valid CAS Registry Number.

-
, (2008/06/13)
There are provided novel nitroguanidine and cyanoguanidine compounds. A method of dessicating and defoliating plants by applying to the foliage thereof certain nitroguanidine or cyanoguanidine compounds and a method for the selective preemergence control of undesirable broadleaf weeds and grasses in the presence of graminaceous crops are disclosed.
