Molecular Formula
C2H5Cl
Molecular Weight
64.51  g/mol
InChI Key
HRYZWHHZPQKTII-UHFFFAOYSA-N
FDA UNII
46U771ERWK

A gas that condenses under slight pressure. Because of its low boiling point ethyl chloride sprayed on skin produces an intense cold by evaporation. Cold blocks nerve conduction. Ethyl chloride has been used in surgery but is primarily used to relieve local pain in sports medicine.

4 Drug and Medication Information
4.1 Therapeutic Uses

Anesthetics, Local

National Library of Medicine's Medical Subject Headings online file (MeSH, 1999)


Ethyl chloride is applied topically as a spray.

McEvoy, G.K. (ed.). AHFS Drug Information 90. Bethesda, MD: American Society of Hospital Pharmacists, Inc., 1990 (Plus Supplements 1990)., p. 2051


For use in local anesthesia ... /and/ used as a counterirritant ... .

McEvoy, G.K. (ed.). AHFS Drug Information 90. Bethesda, MD: American Society of Hospital Pharmacists, Inc., 1990 (Plus Supplements 1990)., p. 2051


MEDICATION (VET): Use of ethyl chloride ... restricted to the cat. ... May also be used to anesthetize birds. ... /Also/ for parakeets and canaries ... .

Booth, N.H., L.E. McDonald (eds.). Veterinary Pharmacology and Therapeutics. 5th ed. Ames, Iowa: Iowa State University Press, 1982., p. 196

4.2 Drug Warning

Because ethyl chloride is highly flammable, it should not be used in areas where ignition may occur. ... The drug should not be applied to broken skin or mucous membranes. During application of ethyl chloride, the skin adjacent to the area being treated should be covered with petrolatum to protect against tissue sloughing. ... Caution must be observed to avoid spilling the liquid on the skin. ... Deep general anesthesia followed by death has been reported. ... The patient should be observed for delayed nephrotoxicity or hepatotoxicity.

McEvoy, G.K. (ed.). AHFS Drug Information 90. Bethesda, MD: American Society of Hospital Pharmacists, Inc., 1990 (Plus Supplements 1990)., p. 2051


... The drug incr cardiac irritability and causes spontaneous arrhythmias. Asystole may occur before medullary paralysis. For this reason, the use of the drug by inhalation has been abandoned.

5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Anesthetics, Local

Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fiber. In contact with a nerve trunk, these anesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. (From Gilman AG, et. al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed) Nearly all local anesthetics act by reducing the tendency of voltage-dependent sodium channels to activate. (See all compounds classified as Anesthetics, Local.)


5.2 ATC Code

N - Nervous system

N01 - Anesthetics

N01B - Anesthetics, local

N01BX - Other local anesthetics

N01BX01 - Ethyl chloride


5.3 Absorption, Distribution and Excretion

IT IS EASILY ABSORBED THROUGH MUCOUS MEMBRANES AND THE LUNG AND THROUGH THE SKIN. ETHYL CHLORIDE IS QUICKLY ELIMINATED FROM THE BODY; MOST OF THIS ELIMINATION OCCURS THROUGH THE LUNG.

American Conference of Governmental Industrial Hygienists. Documentation of the Threshold Limit Values for Substances in Workroom Air. Third Edition, 1971. Cincinnati, Ohio: American Conference of Governmental Industrial Hygienists, 1971. (Plus supplements to 1979), p. 107


The major portion of an inhaled dose is eliminated unchanged in exhaled breath, but minute traces may remain in the blood for some time ... . Some of the compound is also excreted in the urine, feces, and sweat.

USEPA; Summary Review of Health Effects Associated with Monochloroethane Health Issue Assessment. p 15 (1988) NTIS PB 88-236047


5.4 Metabolism/Metabolites

... Ethyl chloride is not metabolized to a significant degree.

Clayton, G. D. and F. E. Clayton (eds.). Patty's Industrial Hygiene and Toxicology: Volume 2A, 2B, 2C: Toxicology. 3rd ed. New York: John Wiley Sons, 1981-1982., p. 3483


... Dechlorination of a number of chloroethanes ... /was evaluated/ using hepatic microsome preparations from rats. ... For monochloroethane, enzymatic losses of chlorine amounted to less than 0.5 percent of the initial amount of radiolabel used. However, ... some dechlorination (not quantified) occurred in the absence of NADP, suggesting an alternate pathway of metabolism or a nonenzymatic breakdown of the compound.
