Clioquinol is a halogenated hydroxyquinoline with antifungal and antibacterial activity, used topically for skin infections and, historically, as an intestinal antiprotozoal before neurological concerns led to withdrawal from many systemic indications. Simson Pharma's Clioquinol reference standard and impurities support topical-formulation QC and legacy analytical needs.
