LIGHT BROWN TO GREY FINE CRYSTALLINE POWDER | [Uses]
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]

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.] |
