Description

[2-(Methacryloyloxy)Ethyl]Dimethylammonium n-Oxide is a specialized, high-purity zwitterionic monomer with a unique combination of a polymerizable methacrylate group and a permanent betaine structure. This compound is critical for synthesizing advanced polymers that exhibit exceptional anti-fouling properties, high biocompatibility, and superior hydration. It is primarily sought by R&D and production teams in the pharmaceutical, biomedical device, and specialty coatings industries for creating next-generation materials such as non-thrombogenic surfaces, protein-resistant coatings, and super-hydrophilic hydrogels.

Application

• Biomedical Polymers: Key monomer for manufacturing non-fouling, biocompatible coatings on medical devices, implants (e.g., catheters, stents), and diagnostic sensors to prevent protein and bacterial adhesion.
• Hydrogel Synthesis: Essential for creating superabsorbent and highly hydrated hydrogels used in contact lenses, wound dressings, and drug delivery systems.
• Marine & Anti-fouling Coatings: Used in formulating environmentally friendly coatings for ship hulls and underwater structures to inhibit marine organism attachment.
• Personal Care & Cosmetics: Employed in the synthesis of polymers for hair care, skin care, and cosmetic formulations that require excellent moisture retention and skin feel.
• Water Treatment Membranes: Incorporated into polymer membranes to enhance fouling resistance and improve flux in ultrafiltration and reverse osmosis applications.
• Enhanced Oil Recovery (EOR): Used to develop viscosity modifiers and friction reducers for oilfield chemicals that perform in high-salinity environments.
• Chromatography Media: Serves as a functional monomer for producing hydrophilic interaction chromatography (HILIC) stationary phases.
• Adhesives & Sealants: Imparts improved adhesion to wet surfaces and enhanced compatibility in various adhesive formulations.
