  • Applications

    2-(2-((5-Bromo-2-pyridyl)amino)vinyl)-1-ethyl-6-methylpyridinium iodide (CAS 1463-95-2) is typically used as a reactive monomer and dye precursor in polymer and coating systems. The vinyl functionality enables copolymerization to yield polymers and crosslinked networks that embed the cationic pyridinium unit, enhancing adhesion and ionic characteristics in coatings, inks, and adhesives. It also functions as a chromophore for colored or optically active materials, enabling coloration and potential fluorescence or sensing capabilities in electronic or photonic applications. As an organic intermediate, it can serve in the synthesis of other quaternary ammonium dyes and specialty materials for coatings and printed electronics, with use subject to formulation limits and regulatory compliance.
