Technical 4-aminopyridine is a white crystalline solid that contains about 98% active ingredient. It is soluble in water and slightly soluble in benzene and ether. 4-Aminopyridine formulations are classified by the US Environmental Protection Agency (US EPA) as restricted use pesticides (RUPs) and therefore should be purchased and used only by certified and trained workers and applicators. Avitrol is available as grain baits or as a powder concentrate. It is one of the most prominent avicides. It is registered with the EPA for use against red-winged blackbirds, blackbirds in agricultural fields, grackles, pigeons, and sparrows around public buildings, and various birds around livestock feeding pens. Avitrol repels birds by poisoning a few members of a flock, causing them to become hyperactive.

Aminopyridines are N-heterocyclic amines with anti-bacterial and antithrombotic properties that have been used to treat various types of diseases [9]. In particular, 4-aminopyridine is the first drug molecule that is particularly used in the treatment of multiple sclerosis syndromes by blocking the potassium channel [10]. It has two hydrogen bond donors and two hydrogen bond acceptors, while in cationic form; it has three hydrogen bond donors. In general, 4-aminopyridine forms complexes with carboxylic acid, resulting in supra-molecular heterosynthon by establishing either neutral N–H···O or N+–H···O− hydrogen bonds. There are various reports in the literature on co-crystals and salts of 4-aminopyridine [11–16].
