Description

N,N,n-Trimethyl-1-(4-Vinylphenyl)Methanaminium Chloride is a quaternary ammonium salt monomer featuring a polymerizable vinyl group, making it a critical building block for advanced functional materials. Its primary commercial value lies in its ability to impart permanent cationic charge to polymers, which is essential for applications requiring strong electrostatic interactions. This compound is particularly vital for manufacturers in the water treatment, specialty polymer, and personal care industries seeking to develop high-performance flocculants, ion-exchange resins, or antimicrobial coatings.

Application

• Synthesis of Cationic Polyelectrolytes: Key monomer for producing polymers used as flocculants and coagulants in municipal and industrial wastewater treatment.
• Ion-Exchange Resins & Membranes: Used to manufacture resins for water softening, demineralization, and selective ion capture in hydrometallurgy and chemical processing.
• Antimicrobial & Antistatic Coatings: Incorporated into surface coatings for textiles, medical devices, and plastics to provide durable antimicrobial or static-dissipative properties.
• Enhanced Oil Recovery (EOR): A component in polymers designed to modify the viscosity and flow properties of injection water in oilfield operations.
• Paper Retention Aids: Used in the production of cationic polymers that improve retention of fillers and fines in paper manufacturing.
• Personal Care Conditioning Agents: Serves as a precursor for polymers used in hair conditioners and skin creams, where cationic charge improves substantivity to keratin.
• Biomedical Materials: Employed in the development of drug delivery carriers and non-viral gene transfection agents due to its positive charge for binding biomolecules.

Quality Control

Our N,N,n-Trimethyl-1-(4-Vinylphenyl)Methanaminium Chloride is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistency and high purity, meeting the stringent requirements for polymer synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and performance.
