2,4-Dichlorophenol Chemical Properties,Uses,Production

Chemical Properties

white to beige crystalline solid

Chemical Properties

2,4-DCP is a colorless crystalline solid with a characteristic odor


2,4-Dichlorophenol is a chlorinated derivative of phenol and is used as an intermediate for the preparation of herbicide 2,4-dichlorophenoxyacetic acid (D435680).


ChEBI: A dichlorophenol that is phenol carrying chloro substituents at positions 2 and 4.

General Description

Colorless crystalline solid with a medicinal odor. Melting point 45°C. Sinks in water. Strong irritant to tissues; toxic by ingestion.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

2,4-Dichlorophenol can react vigorously with oxidizing agents. Can also react with acids or acid fumes. Incompatible with acid chlorides and acid anhydrides.

Health Hazard

Tremors, convulsions, shortness of breath, inhibition of respiratory system.

Safety Profile

Suspected carcinogen with experimental carcinogenic and teratogenic data. Poison by intraperitoneal route. Moderately toxic by ingestion and subcutaneous routes. An experimental teratogen. Mutation data reported. Combustible when exposed to heat or flame. Can react vigorously with oxidizing materials. To fight fre, use alcohol foam, foam, CO2, dry chemical. When heated to decomposition, or on contact with acid or acid fumes, it emits hghly toxic fumes of Cl-. See also CHLOROPHENOLS.

Potential Exposure

2,4-Dichlorophenol is a commercially produced substituted phenol used in the manufacture of industrial and agricultural products; in synthesis of pharmaceuticals. As an intermediate in the chemical industry, 2,4-DCP is utilized as the feedstock for the manufacture of 2,4-dichlorophenoxyacetic acid (2,4-D), and 2,4-D derivatives (germicides, soil sterilants, etc.); certain methyl compounds used in mothproofing, antiseptics and seed disinfectants. 2,4-DCP is also reacted with benzene sulfonyl chloride to produce miticides or further chlorinated to pentachlorophenol, a wood preservative. It is thus a widely used pesticide intermediate. The only group expected to be at risk for high exposure to 2,4-DCP is industrial workers involved in the manufacturing or handling of 2,4-DCP and 2,4-D

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. Speed in removing material from skin is of extreme importance. Shampoo hair promptly if contaminated. 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. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.


UN2020 Chlorophenols, solid, Hazard Class: 6.1; Labels: 6.1-Poisonous materials

Purification Methods

Crystallise it from pet ether (b 30-40o). Purify it also by repeated zone melting, using a P2O5 guard tube to exclude moisture. It is very hygroscopic when dry. [Beilstein 6 IV 885.]


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. Contact with acids or acid fumes causes decomposition releasing poisonous chlorine gas. Incompatible with caustics, acid anhydrides; acid chlorides. Quickly corrodes aluminum; slowly corrodes zinc, tin, brass, bronze, copper and its alloys. May accumulate static electrical charges, and may cause ignition of its vapors.

Waste Disposal

Dissolve in a combustible solvent and incinerate in a furnace equipped with afterburner and scrubber. In accordance with 40CFR165, follow 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. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≧100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal
