Description
Ethyldichloroarsine is a colorless, mobile liquid with a fruity, biting, and irritating odor. It has a boiling point of 168°F and is denser than water, with vapors heavier than air. The vapor pressure of Ethyldichloroarsine is 2.3 mm at 71°F. It decomposes when exposed to water and attacks brass but not iron (dry). Ethyldichloroarsine is soluble in alcohol, benzene, ether, and water. It is very toxic by inhalation, and its vapors can irritate the eyes and skin.
Uses
1. Used in Chemical Industry:
Ethyldichloroarsine is used as an intermediate in the production of various organoarsenic compounds for the chemical industry. Its ability to decompose by water and its reactivity with other chemicals make it a valuable component in the synthesis of specific chemical products.
2. Used in Research and Development:
Due to its unique chemical properties, Ethyldichloroarsine can be utilized in research and development for the study of organoarsenic compounds and their potential applications in various fields, including pharmaceuticals and materials science.
3. Used in Analytical Chemistry:
Ethyldichloroarsine's reactivity with certain metals and its solubility in various solvents make it a useful reagent in analytical chemistry for the identification and quantification of specific elements or compounds.
4. Used in Warfare and Defense:
Historically, Ethyldichloroarsine has been used as a chemical warfare agent due to its high toxicity by inhalation. However, it is important to note that the use of chemical weapons is prohibited under international law, and this application is not endorsed or supported.
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.
Safety Profile
A human poison by
inhalation. Experimentally, a deadly poison
by inhalation and subcutaneous routes, and
probably by ingestion. A severe irritant. A
mdltary poison gas. Can react with oxidzing
materials. Will react with water or steam to
produce toxic and corrosive fumes.
Dangerous; on contact with acid or acid
fumes it emits highly toxic fumes of Cl-, As,
and phosgene. See also ARSENIC
COMPOUNDS.
Potential Exposure
Organoarsenic compound,
Organometallic.
Shipping
UN1892 Ethyldichloroarsine Hazard class: 6.1;
Labels: 6.1-Poison Inhalation Hazard; Inhalation Hazard
Zone B. Military driver shall be given full and complete
information regarding shipment and conditions in case of
emergency. AR 50-6 deals specifically with the shipment
of chemical agents. Shipments of agent will be escorted in
accordance with AR 740-32
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
Check Digit Verification of cas no
The CAS Registry Mumber 598-14-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 8 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 598-14:
(5*5)+(4*9)+(3*8)+(2*1)+(1*4)=91
91 % 10 = 1
So 598-14-1 is a valid CAS Registry Number.

Disclosed are methods of preparing monoalkyl Group VA metal dihalide compounds in high yield and high purity by the reaction of a Group VA metal trihalide with an organo lithium reagent or a compound of the formula RnM1X3?n, where R is an alkyl, M1 is a Group IIIA metal, X is a halogen and n is an integer fro 1 to 3. Such monoalkyl Group VA metal dihalide compounds are substantially free of oxygenated impurities, ethereal solvents and metallic impurities. Monoalkyl Group VA metal dihydride compounds can be easily produced in high yield and high purity by reducing such monoalkyl Group VA metal dihalide compounds.
