1,8,9-TRIHYDROXYANTHRACENE Usage And Synthesis

Chemical Properties

yellow crystalline powder

Uses

Antipsoriatic.

Definition

ChEBI: An anthracenetriol that is anthracene substituted by hydroxy groups at positions 1, 8 and 9.

brand name

Anthra-Derm (Dermik); DrithoCreme (Dermik); Drithoscalp (Dermik); Lasan (Stiefel).

General Description

Odorless yellow leaflets or needles; yellow powder. Tasteless. Filtrate from water suspension is neutral to litmus. When exposed to air, alkaline solutions turn red and lose their fluorescence.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

1,8,9-TRIHYDROXYANTHRACENE is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides. 1,8,9-TRIHYDROXYANTHRACENE is incompatible with strong oxidizing agents. .

Fire Hazard

Flash point data for 1,8,9-TRIHYDROXYANTHRACENE are not available. 1,8,9-TRIHYDROXYANTHRACENE is probably combustible.

Safety Profile

Questionable carcinogen withexperimental neoplastigenic and tumorigenic data.Mutation data reported. Skin contact can cause folliculitis.Absorption can cause kidney damage and intestinaldisturbances. Combustible when heated. When heated todecompositi

Purification Methods

Crystallise it from pet ether and pKEst  ~dry it in vcuo.[Beilstein 6 IV 7602.]
