Sigma-Aldrich Anthraquinone-2-sulfonic acid sodium salt monohydrate

Anthraquinone-2-sulfonic acid sodium salt monohydrate forms charge-transfer complexes with 9,10-dimethoxyanthracene-2-sulfonate[1].

Anthraquinone-2-sulfonic acid sodium salt monohydrate can be used as a redox indicator to enhance the sensitivity and selectivity of the DNA biosensor.[2]

Anthraquinone-2-sulfonic acid sodium salt monohydrate was used to investigate the effects of reactant concentration and synthesis parameters on the electrical conductivity of polypyrrole coated polyethyleneterephthalate fabrics[3]. It has been used as dopant in the preparation of polypyrrole films by electrochemical polymerization[4].
