Description

1-(3-Sulfopropyl)-2-Vinylpyridinium Betaine is a specialized zwitterionic monomer featuring a reactive vinyl group and a permanent sulfobetaine moiety. This unique structure makes it a critical building block for creating polymers with exceptional anti-fouling, biocompatibility, and hydration properties. It is primarily sought after by R&D and production teams in the advanced materials and life sciences sectors for developing high-performance coatings, hydrogels, and separation membranes.

Application

• Antifouling Surface Coatings: Key monomer for synthesizing zwitterionic polymer brushes and coatings applied to marine vessels, medical devices, and sensors to prevent protein, bacterial, and organic matter adhesion.
• Biomedical Hydrogels: Used in the fabrication of super-hydrophilic, non-cytotoxic hydrogels for wound dressings, drug delivery systems, and tissue engineering scaffolds.
• Chromatography Media: Serves as a functional ligand for creating hydrophilic interaction liquid chromatography (HILIC) stationary phases with tailored selectivity for polar compound separation.
• Enhanced Oil Recovery (EOR): Employed in synthesizing viscosifiers and friction reducers for smart drilling fluids that require high salt tolerance and thermal stability.
• Personal Care & Cosmetics: Incorporated into polymer formulations for hair care and skincare products to provide long-lasting moisturization and a superior sensory feel.
• Water Treatment Membranes: Used to modify membrane surfaces (e.g., reverse osmosis, ultrafiltration) to significantly improve fouling resistance and water flux.

Quality Control

Our 1-(3-Sulfopropyl)-2-Vinylpyridinium Betaine is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including NMR, HPLC, and elemental analysis, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after initial use to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
