Chemical Properties
Colorless, mobile liquid; becomes yellowish under the action of light and air. Fruitlike odor (high dilution). Decomposed by water.
Attacks brass but not iron (dry). Soluble in alcohol, benzene, ether, and
water.
General Description
A colorless liquid with a fruity biting irritating odor. Vapors irritate eyes and skin. Very toxic by inhalation. Boiling point 168°F. Denser than water and vapors are heavier than air. Vapor pressure 2.3 mm at 71°F.
Air & Water Reactions
Reacts with water or moist air to form hydrochloric acid or fumes of hydrogen chloride.
Reactivity Profile
ETHYL DICHLOROARSINE is a reducing agent. Reacts rapidly and dangerously with oxygen and with other oxidizing agents, even weak ones. Likely to ignite on contact with alcohols. Incompatible with acids, alcohols, amines, and aldehydes. May be ignited by heat, sparks or flames. May re-ignite after fire is extinguished.
Health Hazard
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways.
Hazard
Toxic by ingestion, inhalation, and skin
absorption; strong irritant.
Potential Exposure
Organoarsenic compound,
Organometallic.
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at
least 30 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. 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.
Medical observation is recommended for 24 to 48 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. Keep victim quiet and maintain normal body temperature. Effects may be delayed;
keep victim under observation.
Shipping

Incompatibilities
Reacts with water or moist air releasing
hydrochloric acid and/or corrosive fumes of hydrogen chloride (HCl). A 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, and epoxides.
Attacks some metals; brass, but not ferrous metals
Waste Disposal
Use a licensed professional
waste disposal service to dispose of this material. Dissolve
or mix the material with a combustible solvent and burn in
a chemical incinerator equipped with an afterburner and
scrubber. All federal, state, and local environmental regulations must be observed.
