Diamond Hazard Value Description
3 1
Health   3 Short exposure could cause serious temporary or moderate residual injury (e.g. liquid hydrogen, sulfuric acid, calcium hypochlorite, hexafluorosilicic acid)
Flammability   0 Materials that will not burn under typical fire conditions, including intrinsically noncombustible materials such as concrete, stone, and sand. Materials that will not burn in air when exposed to a temperature of 820 °C (1,500 °F) for a period of 5 minutes.(e.g. Carbon tetrachloride)
Instability   1 Normally stable, but can become unstable at elevated temperatures and pressures (e.g. propene)

Chloroacetyl chloride Chemical Properties,Uses,Production

Chemical Properties

Clear colorless liquid

Chemical Properties

Chloroacetyl chloride is a colorless to yellowish liquid with a very pungent, extremely irritating, odor.


In the synthesis of organic compounds.


A lachrymator.

General Description

A colorless to light yellow liquid with a very pungent odor. Very toxic by inhalation. Corrosive to metals and tissue.

Reactivity Profile

Chloroacetyl chloride reacts rapidly with water. Incompatible with strong oxidizing agents, alcohols, bases (including amines). May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].


Irritant to eyes, corrosive to skin. Upper respiratory tract irritant.

Health Hazard

Inhalation causes severe irritation of upper respiratory system. External contact causes severe irritation of eyes and skin. Ingestion causes severe irritation of mouth and stomach.

Safety Profile

Poison by ingestion and intravenous routes. Mildly toxic by inhalation. Corrosive. A lachrymator. When heated to decomposition it emits toxic fumes of Cl-.

Potential Exposure

Highly toxic by inhalation. Chloroacetyl chloride is used in the manufacture of acetophenone. It is used in the manufacture of a number of pesticides including: alachlor, allidochlor, butachlor, dimethachlor, formothion, mecarbam, metolachlor, propachlor. It is also used in the manufacture of pharmaceuticals, such as chlordiazepoxide hydrochloride, diazepam, lidocaine, mianserin.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 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. 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. If victim is conscious, administer water or milk. Do not induce vomiting. 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.


UN1752 Chloroacetyl chloride, Hazard class: 6.1; Labels: 6.1-Poison Inhalation Hazard, 8-Corrosive material, Inhalation Hazard Zone B.


Reacts violently with water, steamforming chloroacetic acid and hydrogen chloride gas. Reacts with alcohols, powdered metals; sodium amide; combustibles; and many organics, causing toxic fumes, fire, and explosion hazard. On contact with air it emits corrosive gas. Decomposes when heated forming phosgene gas. Corrosive to metals.

Waste Disposal

It may be discharged into sodium bicarbonate solution, then flushed to the sewer with water.
