GtoPdb Ligand ID: 2313

PDB Ligand
Compound class: Synthetic organic
Comment: While the INN-assigned preparation of dequalinium is in complex with chloride, the compound is also available experimentally as the 'parent' salt form. Two of the references listed here [1,4] refer to the parent compound, while [5] and [6] refer to dequalinium chloride. We show the structure of the parent compound, and our external links are also to this structure.
