Chlorohydroquinone Chemical Properties,Usage,Production

Chemical Properties

light brown to grey fine crystalline powder. It precipitates leafy crystals from chloroform and needle-like crystals from toluene. Freely soluble in water and alcohol, slightly soluble in ether and hot chloroform.

Uses

Chlorohydroquinone is a component of polyethers based on organotin with potential application to breast cancer treatment via growth inhibition. Also a component in the synthesis of contraceptive agents in pharmaceutical compounds. It is also used within hydroxylation and catalysis organic reactions in the synthesis of pharmacologically active phenolic compounds.

Preparation

Chlorohydroquinone is obtained by reacting p-benzoquinone with hydrochloric acid. First dissolve p-benzoquinone with chloroform and pass dry hydrogen chloride gas under cooling to obtain.

Application

Chlorohydroquinone is a benzenediol that consists of hydroquinone bearing a single chloro substituent. It has a role as a metabolite. It is a member of monochlorobenzenes and a member of chlorohydroquinones. Chlorohydroquinone is used in photographic developing solutions. It is also a bactericide.

Definition

ChEBI: Chlorohydroquinone is a benzenediol that consists of hydroquinone bearing a single chloro substituent. It has a role as a metabolite. It is a member of monochlorobenzenes and a member of chlorohydroquinones.

Safety Profile

Poison by ingestion and intraperitoneal routes. Moderately toxic by skin contact. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of Cl-. See also CHLORIDES.

Purification Methods

Crystallise the hydroquinone from CHCl3 or toluene. [Beilstein 6 IV 5767.]
