79-43-6

A colorless crystalline solid melting at 49°F. Corrosive to metals and tissue.

DICHLOROACETIC ACID(79-43-6) is probably hygroscopic. This chemical reacts with water or steam. DICHLOROACETIC ACID(79-43-6) is incompatible with strong oxidizing agents, strong bases and strong reducing agents.

Soluble in water.

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. 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.

This haloacetic acid can be a byproduct of drinking water disinfection and may increase the risk of cancer. This chemical is used as starting material for the production of glyoxylic; dialkyloxy acids; and sulfonamides. It is also used as a fungicide, a medication; and a chemical intermediate in pharmaceuticals

Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.

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.

DCA is a corrosive, combustible, colorless liquid with a pungent odor.

Dichloroacetic acid, CHCI2COOH, also known as dichlorethanoic acid, is a colorless,strong liquid acid. It is soluble in water and alcohol. Dichloroacetic acid is prepared by the chlorination of acetic acid.It is used in organic synthesis.

Dichloroacetic acid is used as an intermediate to make other chemicals such as its salts and esters. It is involved as a test reagent for fiber analysis and a disinfectant. It is used to inhibit mitochondrial PDK (pyruvate dehydrogenase kinase) and to shift cellular metabolism from glycolysis to glucose oxidation. Further, it is used in the treatment for post-ischemic recovery.

Dichloroacetic acid (DCA) is a chlorinated acetic acid that has been reported to be a mouse liver carcinogen. The varying degrees of swelling of polyester in different concentrations of DCA solution has been analyzed by phase-contrast microscopy. The efficiency of titanium dioxide (TiO2) nanoparticles to catalyze the photodegradation of DCA has been investigated.
Dichloroacetic acid (DCA) can be used as:
A reactant in the synthesis of chloroketones by reacting with esters in the presence of LiHMDS via Claisen-type homologation reaction.
A structure-directing agent, solvent, or plastdopant for the preparation of different morphologies of polyaniline (PANI). Self-assembling nanostructured PANI may be formed due to the presence of strong hydrogen bonding between DCA and aniline/polyaniline.

ChEBI: An organochlorine compound comprising acetic acid carrying two chloro substituents at the 2-position. It occurs in nature in seaweed, Asparagopsis taxiformis.

Dichloroacetic acid was reported to be first synthesized in 1864 by the further chlorination of monochloroacetic acid with chlorine (Beilstein Online, 2002). The most common production method for dichloroacetic acid is the hydrolysis of dichloroacetyl chloride, which is produced by the oxidation of trichloroethylene.

Color Code—White: Corrosive or Contact Hazard;Store separately in a corrosion-resistant location. Prior toworking with DCA you should be trained on its proper handling and storage. Store in tightly closed containers in acool, well-ventilated area away from incompatible materialslisted above. Metal containers involving the transfer of thischemical should be grounded and bonded. Where possible,automatically pump liquid from drums or other storage containers to process containers. Drums must be equipped withself-closing valves, pressure vacuum bungs, and flamearresters. Use only nonsparking tools and equipment, especially when opening and closing containers of this chemical. Sources of ignition, such as smoking and open flames,are prohibited where this chemical is used, handled, orstored in a manner that could create a potential fire orexplosion hazard. Wherever this chemical is used, handled,manufactured, or stored, use explosion-proof electricalequipment and fittings.

Crystallise this strong acid from *benzene or pet ether. Dry it with MgSO4 and fractionally distil it. [Bernasconi et al. J Am Chem Soc 107 3612 1985, Beilstein 2 IV 498.]

The initial risk screening level (IRSL) for dichloroacetic acid (DCA) is 0.07 μg/m3 (annual averaging time) based on the Michigan Department of Environmental Quality (MDEQ), Air Quality Division (AQD) Rule 336.1231. The initial threshold screening level (ITSL) is 0.5 μg/m3 (annual averaging time) based on Rule 336.1232 (1) (e) and (2) (c).
