Description

2-[[2-(Methacryloyloxy)Ethyl]Dimethylammonio]Acetate is a specialized zwitterionic monomer featuring a methacrylate group and a quaternary ammonium carboxylate betaine structure. This unique molecular architecture provides exceptional properties for creating advanced polymeric materials with permanent dipole moments and high polarity. It is a critical raw material for manufacturers seeking to engineer polymers with specific surface characteristics, enhanced biocompatibility, and tunable hydrophilicity. Key industries that utilize this monomer include advanced polymer synthesis, biomedical materials, and specialty coatings.

Application

• Synthesis of Zwitterionic Polymers: Primary monomer for creating polybetaines with anti-fouling and protein-resistant properties.
• Biomedical & Healthcare Materials: Used in the production of hydrogels for contact lenses, wound dressings, and drug delivery systems due to its biocompatibility and moisture retention.
• Anti-fouling Coatings: A key component in marine coatings, medical device coatings, and membrane surfaces to prevent biofilm formation and protein adsorption.
• Personal Care & Cosmetics: Incorporated into hair care and skincare formulations to improve conditioning, moisture balance, and skin feel in polymers.
• Enhanced Oil Recovery (EOR): Used in polymer flooding applications to modify the viscosity and interfacial properties of injection fluids.
• Chromatography Media: Serves as a functional monomer for preparing hydrophilic interaction chromatography (HILIC) stationary phases.
• Sensors and Diagnostic Devices: Employed to create sensitive polymer layers that respond to specific biological or chemical stimuli.

Quality Control

Our 2-[[2-(Methacryloyloxy)Ethyl]Dimethylammonio]Acetate is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay by HPLC, identification by FT-IR and NMR, and quantification of key impurities such as residual monomers and solvents. We provide full traceability and Certificates of Analysis (COA) are available for all shipments to ensure compliance with your formulation and regulatory requirements.

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). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed after opening to minimize exposure to atmospheric moisture and light. Keep away from incompatible materials such as strong oxidizing agents.
