2,6-DPPEAQ (Anthraquinone Bis(propylphosphonic Acid)), ≥90%

Cat No:BME-0104

Description

2,6-DPPEAQ pairs the reversible two-electron redox chemistry of the anthraquinone core with two propylphosphonic acid groups, and that pairing is what makes it practical in a flow cell. The phosphonate tails raise aqueous solubility dramatically without resorting to corrosive acid, so the molecule can be cycled at near-neutral pH where system hardware lasts longer. It is normally paired against a ferrocyanide or ferrocene posolyte to build an all-organic aqueous flow battery. The material is shipped and stored cold because the hydroquinone form oxidises slowly in warm air. Minimum assay is 90%, and it is handled as a skin and eye irritant.
