1,5-Naphthalenedisulfonic acid is a diazonium salt that is used in wastewater treatment. It can be used in the presence of hydrogen bonding interactions to remove contaminants from wastewater. This chemical has been shown to be effective in biological treatment systems and fluorescence detector applications. 1,5-Naphthalenedisulfonic acid has been shown to react with 2,4-dichlorobenzoic acid to form a coordination complex with a structure that contains two nitrogen atoms and one proton on each side of the central carbon atom. The frequency shift between these two atoms has been determined to be at least 200 MHz. The coordination geometry is octahedral, which means there are six different positions for the proton.
