What is 1,8,9-TRIHYDROXYANTHRACENE?
Chemical properties
yellow crystalline powder
The Uses of 1,8,9-TRIHYDROXYANTHRACENE
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
