The Uses of Diethylcarbamyl chloride

It is used in the production of pharma ingredients. It is a reagent in the synthesis of S-Methyl-N,N-diethylthiocarbamate Sulfoxide, which is an oxygenated metabolite of Disulfiram (Antabuse) that is capable of in vitro inactivation of liver mitochondrial aldehyde dehydrogenase.

Safety Profile

Suspected carcinogen with experimental carcinogenic data. Moderately toxic by intraperitoneal route. Mutation data reported. Reacts with water or steam to produce toxic and corrosive fumes. When heated to decomposition it emits highly toxic fumes of Cl and NOx. See also CARBATMATES and CHLORIDES.

Toxicology

The median lethal dose (LD50) upon oral administration to rats is about 200 mg/kg. The compound is irritating to skin and eyes. The inhalation of an atmosphere saturated with its vapors at 20℃ is lethal to rats after 3 h. Diethylcarbamoyl chloride has proved to be mutagenic on E. coli strains in mutagenicity tests. It is weakly mutagenic in high doses in the Ames test. In view of these results and on account of the structural similarity to dimethylcarbamoyl chloride, a carcinogenic potential cannot be ruled out. The MAK commission has listed this substance in group III B.

Potential Exposure

Diethylcarbamazine citrate, a carbamate anthelmintic (working agent), used in the synthesis ofpharmaceuticals.

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. If victim is conscious, administer water ormilk. Do not induce vomiting.

storage

Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, wellventilated area away from oxidizers and reducing agents.Where possible, automatically pump liquid from drums orother storage containers to process containers. A regulated,marked area should be established where this chemical ishandled, used, or stored in compliance with OSHAStandard 1910.1045.

Shipping

Toxic liquids, water-reactive, n.o.s. require a labelof “POISONOUS/TOXIC MATERIALS, DANGEROUSWHEN WET.” They fall in Hazard Class 6.1.

Incompatibilities

Will react with water or steam to producetoxic and corrosive fumes.
