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