Anthraquinone-2,7-Disulfonic Acid Disodium Salt CAS 853-67-8 Desulfurization Agent 392.33 g/mol Red Powder
Anthraquinone-2,7-Disulfonic Acid Disodium Salt (CAS 853-67-8) is a specialized desulfurization agent available in powder form. This white powder exhibits moisture absorption properties and forms acidic aqueous solutions. The solid remains stable under dry conditions, while neutral or weakly acidic aqueous solutions can be stored at room temperature for up to 7 days. Exposure to alkali and heat accelerates deterioration and decomposition.
The compound features a specific rotation [α] 23D-34.8° (1%, water) and demonstrates maximum absorption at wavelengths of 260nm and 340nm in aqueous solution. It is readily soluble in water but insoluble in organic solvents including acetonitrile.
