1-Aminopyridinium iodide

1-Aminopyridinium iodide, a pyridine derivative, is an important reagent for organic synthesis. It has various pharmaceutical applications. It participates in homogeneous transition metal-catalyzed reactions. Single-crystal X-ray diffraction studies suggest that the compound crystallizes in the monoclinic space group P21/c (phase II). Aza-ylide derived from 1-aminopyridinium iodide serves as a commercially available ammonia equivalent during the preparation of primary amines. 1-Aminopyridinium iodide may be used in the preparation of room temperature ionic liquids (organic salts in liquid state at room temperature). It may also be used for the preparation of oligomycin A annelated with pyrazolo[1,5-a]pyridine.
