The Uses of 1-Aminopyridinium iodide

1-Aminopyridinium iodide is a reagent used as a building block to construct fused heterocycles, synthesis of substituted pyridines, dipolar cycloadditions, ylide type reactions.

General Description

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.
