Physical description & handling notes

• Light yellow crystalline powder; [MSDSonline]
• 1-Mono anthraquinonesulfonic acid, sodium salt, has a water solubility of 1000 mg/100 ml water at 18 °C.
• Anthraquinonesulfonic acids are strong acids which are readily soluble in water. /Anthraquinonesulfonic acids/

Documented Uses

• Anthraquinonesulfonic acids have commercial value because the sulfonic acid group can be replaced by many nucleophiles; [HSDB]
• Anthraquinonesulfonic acids are commercially important ... major value is due to the relatively easy replacement of the sulfonic acid group by many nucleophiles affording economically valuable intermediates which are difficult to obtain by other methods. /Anthraquinonesulfonic acids/
• Sodium salt, also called silver salt, is prepared by sulfonation of anthraquinone in the absence of mercury. The acid also can be obtained from the 1,6- (or 1,7-) disulfonic acid by desulfonation at the alpha position in dilute sulfuric acid. /Anthraquinone-2-sulfonic acid, sodium salt/
• 1-Anthracenesulfonic acid, 9,10-dihydro-9,10-dioxo-, sodium salt (1:1): ACTIVE
• Quinones (ie, 6,12-dione) have been shown to undergo oxidation-reduction cycles involving quinone, hydroquinone, and molecular oxygen, resulting in the formation of oxygen radicals and semiquinone radicals. /Quinones/
