4-Aminopyridine Chemical Properties,Usage,Production

Chemical Properties
Dalfampridine is used in characterizing subtypes of potassium channel, and has also been used 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. Dalfampridine is a precursor to the drug Pinacidil.
ChEBI: An aromatic amine that is pyridine bearing a single amino substituent at position 4. An orphan drug in the US, it is used to improve walking in adults with multiple sclerosis.
General Description
White crystalline material with no odor. Used as an avicide, an intermediate and as a fixer for some textile dyes.
Reactivity Profile
4-Aminopyridine neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
Health Hazard
Material may be fatal if inhaled, swallowed or absorbed through skin. Contact may cause burns to skin and eyes. Material affects neural transmission. In sufficient concentrations, material may cause metabolic acidosis, respiratory arrest, and cardiac arrhythmias.
Fire Hazard
Material may produce irritating or poisonous gases in fire. Runoff from fire control water may give off irritating or poisonous gases.
