593-89-5 Usage
Chemical Properties
A colorless, mobile liquid; agreeableodor. Decomposed by water.
Uses
Military poison, intermediate.
General Description
A colorless liquid with an agreeable odor. Denser than water. Very toxic by inhalation. Painful burns on contact.
Air & Water Reactions
Decomposes slowly in water to form a corrosive solution of HCl.
Reactivity Profile
Methyldichloroarsine. is a reducing agent. Reacts rapidly and dangerously with oxygen and with other oxidizing agents, even weak ones. Can 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. In one instance, reaction with chlorine rapidly produced gaseous chloromethane, which led to an over pressurization failure [J. Chem. Soc., Dalton Trans., 1976, 1479].
Hazard
Toxic. Highly irritant.
Health Hazard
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Contact with molten substance may cause severe burns to skin and eyes. 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
Combustible material: may burn but does not ignite readily. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
Safety Profile
Poison irritant to skin,
eyes, and mucous membranes and poison by
ingestion and inhalation. A blistering type of
military poison. It is rapidly detoxified in the
body. A moderately persistent gas.
Combustible when exposed to heat or
flame. To fight fire, use water, foam, CO2,
dry chemical. Explosive reaction with
chlorine. Can react vigorously with oxidizing
materials. Dangerous; when heated to
decomposition or on contact with acid or
acid fumes it emits hghly toxic fumes of Cl
and As. See also CHLOROVINYLARSINE
DICHLORIDE and ARSENIC
COMPOUNDS.
Check Digit Verification of cas no
The CAS Registry Mumber 593-89-5 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 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 593-89:
(5*5)+(4*9)+(3*3)+(2*8)+(1*9)=95
95 % 10 = 5
So 593-89-5 is a valid CAS Registry Number.
InChI:InChI=1/CH3AsCl2/c1-2(3)4/h1H3
