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 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.
Chlorohydroquinone is used in photographic developing solutions. It is also a bactericide.

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.

Application

Definition

ChEBI: A benzenediol that consists of hydroquinone bearing a single chloro substituent.

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.

Purification Methods

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