General description

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

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

Application

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. It has been used as dopant in the preparation of polypyrrole films by electrochemical polymerization.
