Sodium Anthraquinone-2,7-Disulfonate (CAS 853-67-8), also known as Anthraquinone-2,7-disulfonic acid disodium salt, is a high-performance redox-active organic compound. In Elemental Derivatives hierarchy (Sulfur/Oxygen/Aromatic path), it serves as a critical "Electron Shuttle." 2-7 AQDS's unique ability to undergo reversible oxidation-reduction (redox) cycles makes it indispensable for large-scale industrial gas purification and emerging energy storage technologies. In the Metallurgy and Energy sectors-a primary catalyst for the removal of hydrogen sulfide (HS) from gas streams, converting toxins into elemental sulphur. For CDMOs and scientists, this molecule is a foundational electrolyte for next-generation Aqueous Organic Flow Batteries (AOFBs), offering a sustainable, non-metal alternative to vanadium-based systems to buy CAS 853-67-8 bulk. We are a globally established speciality chemical, fine chemical & intermediates manufacturer and End to END formulator leadership giant through comprehensive regulatory documentation (CoA), traceability, and consistent global supply capabilities, ensuring reliable lead times and quality assurance across all grades.
