Description

3-[Bis[2-(Methacryloyloxy)Ethyl](Methyl)Ammonio]Propane-1-Sulfonate is a specialized zwitterionic monomer featuring both a polymerizable methacrylate group and a permanent sulfobetaine moiety. This unique structure is critical for imparting permanent hydrophilicity, anti-fouling properties, and excellent biocompatibility to polymeric materials. It is an essential raw material for advanced material scientists and formulators developing high-performance coatings, hydrogels, and medical devices that require superior surface properties and stability.

Application

• Hydrophilic and Anti-fouling Coatings: A key monomer for creating non-fouling surfaces on marine coatings, biomedical implants, and filtration membranes to prevent protein adsorption and biofilm formation.
• Biocompatible Hydrogels: Used in the synthesis of superabsorbent, non-cytotoxic hydrogels for contact lenses, wound dressings, and drug delivery systems.
• Surface Modification of Polymers: Employed to graft permanent hydrophilic layers onto substrates like polyurethane, silicone, and polyethylene to enhance wettability and biocompatibility.
• Chromatography Media: Serves as a functional monomer for producing zwitterionic stationary phases in HPLC, offering unique selectivity for separating polar compounds.
• Personal Care & Cosmetics: Incorporated into formulations for hair styling polymers and skin care products to improve feel, moisture retention, and compatibility.
• Enhanced Oil Recovery (EOR): Utilized in synthesizing polymers for viscosity modifiers and surfactants that improve oil displacement efficiency in challenging reservoirs.

Quality Control

Our 3-[Bis[2-(Methacryloyloxy)Ethyl](Methyl)Ammonio]Propane-1-Sulfonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and compliance with high-purity standards suitable for research and advanced material synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at temperatures between 2°C and 8°C (refrigerated) to maximize shelf life and inhibit premature polymerization. Keep away from heat, sparks, and open flame. Allow the container to reach ambient temperature before opening to prevent moisture condensation.
