Poison by ingestion,

intravenous routes. When heated to
decomposition it emits very toxic fumes of
NO, and SOx. See also THIOCYANATES. | [Hazardous Substances Data]
542-90-5(Hazardous Substances Data) |
| Hazard Information | Back Directory | [General Description]
Liquid. Used as an agricultural insecticide. | [Reactivity Profile]
Nitric acid violently oxidized a thiocyanate solution [Bretherick, 1979 p. 121]. Caution should be exercised in treating a thiocyanate with an oxidizing agent such as a peroxide or chlorate as such mixtures have been known to explode. | [Health Hazard]
This material is highly toxic if ingested. | [Potential Exposure]
This thiocyanate material is used as an
agricultural insecticide | [Fire Hazard]
When heated to decomposition, ETHYLTHIOCYANATE emits very toxic fumes of oxides of nitrogen and sulfur. | [First aid]
Treatment is as for aliphatic thiocyanates.
Because cyanide is probably largely responsible for poisonings; antidotal measures against cyanide should be instituted promptly, for including moving the victim to fresh
air. Call emergency medical care. If not breathing, give
artificial respiration. IF breathing is difficult, give oxygen.
In case of contact with material, immediately flush skin or
eyes with running water for at least 15 minutes. Speed in
removing material from skin is of extreme importance.
Remove and isolate contaminated clothing and shoes
at the site. Keep victim quiet and maintain normal body
temperature. Effects may be delayed; keep victim under
observation | [Shipping]
UN2929 Toxic liquids, flammable, organic,
n.o.s., Hazard class: 6.1; Labels: 6.1-Poison Inhalation
Hazard, 3-Flammable liquid, Technical Name Required | [Incompatibilities]
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. Esters are generally
incompatible with nitrates. Moisture may cause hydrolysis
or other forms of decomposition. Caution should be exercised in treating a thiocyanate with an oxidizing agent such
as a peroxide or chlorate as such mixtures have been
known to explode | [Chemical Properties]
clear colorless liquid | [Chemical Properties]
Ethyl thiocyanate is a liquid. Onion odor | [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 | [Uses]
Ethyl thiocyanate was used in the synthesis of hydrogen cyanide by undergoing in situ reduction with dithiothreitol. | [Purification Methods]
Fractionally distil the ester at atmospheric pressure. [Beilstein 2 IV 1218.] (CARE LACHRYMATOR.) |
