Description

1-(3-Sulfopropyl)-2-Vinylpyridinium Betaine is a specialized zwitterionic monomer, also known as a sulfobetaine, characterized by its unique combination of a vinyl group for polymerization and a permanent positive and negative charge within the same molecule. This structure is critical for imparting exceptional properties like permanent hydrophilicity, anti-fouling characteristics, and biocompatibility to polymeric materials. It is an essential building block for manufacturers in advanced material science, particularly those developing high-performance coatings, biomedical devices, and separation membranes who require reliable, high-purity raw materials to ensure consistent product performance.

Application

• Hydrophilic & Anti-fouling Coatings: A key monomer for creating non-fouling polymer brushes and surface modifications on marine coatings, medical implants, and sensor surfaces to prevent protein and bacterial adhesion.
• Biomedical Polymers: Used in the synthesis of hydrogels, contact lenses, and drug delivery systems where biocompatibility and reduced non-specific protein adsorption are paramount.
• Chromatography Media: Serves as a functional ligand for hydrophilic interaction liquid chromatography (HILIC) stationary phases, improving the separation of polar compounds.
• Enhanced Oil Recovery (EOR): Employed in the synthesis of zwitterionic polymers that act as viscosifiers and friction reducers in challenging reservoir conditions.
• Personal Care & Cosmetics: Incorporated into polymers for hair care and skincare formulations to provide long-lasting moisturization and a soft, non-irritating feel.
• Water Treatment Membranes: Modifies membrane surfaces to increase hydrophilicity, thereby improving water flux and reducing fouling in ultrafiltration and reverse osmosis applications.

Quality Control

Every batch of 1-(3-Sulfopropyl)-2-Vinylpyridinium Betaine is manufactured and tested under a strict quality management system. We ensure consistent high purity and performance through rigorous analytical controls, including NMR, HPLC, and titration methods. A comprehensive Certificate of Analysis (COA) detailing identity, assay, impurity profile, and physical properties is provided with each shipment to guarantee compliance with your specifications and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Keep away from incompatible materials.
