Description
Methoxyethylmercuric acetate is a crystalline solid. Molecular weight= 318.74; Freezing/Melting point=41℃. Hazard Identification (based on NFPA-704 M Rating System): Health 3, Flammability 1, Reactivity 0. Soluble in water.
Chemical Properties
Methoxyethylmercuric acetate is a crystalline
solid.
Definition
A
fungicide and disinfectant used in treating seeds.
General Description
Crystals. Formerly used as a pesticide in seed treatment for cotton and small grains. Exhibits high fungicidal activity against leaf stripe of barley, stinking smut of wheat, snow mold of rye; against seedling diseases in beets and legumes, and for dressing "seed" potatoes, bulbs, and tubers. Not registered as a pesticide in the U.S.
Reactivity Profile
Organometallics, such as METHOXYETHYL MERCURIC ACETATE, are reactive with many other groups. Incompatible with acids and bases. Organometallics are good reducing agents and therefore incompatible with oxidizing agents. Often reactive with water to generate toxic or flammable gases.
Health Hazard
Highly toxic. Target organs are brain and central nervous system. Inhalation can cause lung damage; ingestion can cause kidney damage. Women of childbearing age and persons with eczema, renal or neurological disorders should not be exposed to mercurials.
Fire Hazard
When heated to decomposition, Methoxyethyl mercury acetate emits toxic fumes of mercury. Methoxyethyl mercury acetate may burn but does not ignite readily. Container may explode in heat of fire.
Safety Profile
Poison by ingestion.
Mutation data reported. A fungicide. When
heated to decomposition it emits toxic
fumes of Hg. See also MERCURY
COMPOUNDS.
Potential Exposure
Used as a pesticide in seed treatment for cotton and small grains. It is no longer approved for this use. It exhibits high fungicidal activity against leaf stripe of barley, stinking smut of wheat, snow mold of rye, against seedling diseases in beets and legumes, and for dressing “seed” potatoes, bulbs, and tubers. Not registered as a pesticide in the United States
First aid
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 min, 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 Methoxyethylmercuric acetate 1739 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. Antidotes and special procedures for medical personnel: The drug NAP (n-acetyl penicillamine) has been used to treat mercury poisoning, with mixed success. Note to physician: For severe poisoning BAL [British AntiLewisite, dimercaprol, dithiopropanol (C3H8OS2)] has been used to treat toxic symptoms of certain heavy metals poisoning including mercury. Although BAL is reported to have a large margin of safety, caution must be exercised, because toxic effects may be caused by excessive dosage. Most can be prevented by premedication with 1-ephedrine sulfate (CAS: 134-72-5).
storage
Color Code—Blue: Health Hazard/Poison: Store in a secure poison location. Prior to working with this chemical you should be trained on its proper handling and storage. Store in tightly closed containers in a cool, wellventilated area.
Shipping
UN2025 Mercury compounds, solid, n.o.s.,
Hazard Class: 6.1; Labels: 6.1-Poisonous materials,
Technical Name Required. UN2777 Mercury based pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous
materials, Technical Name Required.
Incompatibilities
Strong reducing agent. Incompatible
with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from
alkaline materials, strong bases, strong acids, oxoacids,
epoxides. Compounds of the carboxyl group react with all
bases, both inorganic and organic (i.e., amines) releasing
substantial heat, water and a salt that may be harmful.
Incompatible with arsenic compounds (releases hydrogen
cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides (releasing heat,
toxic, and possibly flammable gases), thiosulfates and
dithionites (releasing hydrogen sulfate and oxides of
sulfur). Corrosive to iron and other metals.
Waste Disposal
In accordance with 40CFR
165 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.
