Description

12-Pyridin-1-Ium-1-Yldodecyl 2-Methylprop-2-Enoate,Bromide is a specialized quaternary ammonium salt monomer, also known as a polymerizable surfactant or surfmer. This compound matters for its unique dual functionality, combining a cationic pyridinium head group with a polymerizable methacrylate moiety, enabling it to act as both a surfactant and a co-monomer in polymerization reactions. It is primarily needed by R&D chemists and formulators in the polymer, coatings, and advanced materials industries for creating stable emulsions, surface-modified nanoparticles, and functional polymers with tailored properties.

Application

• Emulsion Polymerization: Acts as a reactive surfactant (surfmer) to stabilize polymer particles during synthesis, reducing the need for conventional surfactants and improving film properties.
• Surface Modification Agent: Used to functionalize the surface of nanoparticles (e.g., silica, quantum dots) and carbon nanotubes to enhance dispersion and compatibility in polymer matrices.
• Antimicrobial Coatings: Serves as a building block for creating cationic polymers with inherent antimicrobial activity for use in medical devices and protective coatings.
• Gene Delivery Systems: Investigated in biomedical research for the development of cationic lipid-like carriers for nucleic acid delivery.
• Ion-Exchange Materials: A precursor for synthesizing polymers with pyridinium groups for use in membranes, water treatment, and catalysis.
• Adhesive & Sealant Formulations: Imparts improved adhesion to polar substrates and stability in aqueous-based formulations.
