4-Aminopyridine (CAS: 504-24-5) is one of the three isomeric amines of pyridine, is a highly pure, synthetic, and biologically active compound, widely used in organic synthesis, synthesis of pharmaceutical intermediates and Active Pharmaceutical Ingredient (API) synthesis. 4-Aminopyridine (4-AP, Fampridine, Dalfampridine) is used as a research tool in characterizing subtypes of the potassium channel. It has also been used as a drug, to manage some of the symptoms of multiple sclerosis, and is indicated for symptomatic improvement of walking in adults with several variations of the disease. The U.S. Food and Drug Administration (FDA) approved the compound on January 22, 2010. Fampridine is also marketed in the United States by Acorda Therapeutics and as Fampyra in the European Union, Canada, and Australia.
