Description

n-(2-Hydroxyethyl) Methacrylamide CAS NO 5238-56-2 is a versatile bifunctional monomer featuring both a polymerizable methacrylamide group and a reactive hydroxyl group. This unique structure makes it a critical building block for synthesizing advanced polymers with tailored properties, such as enhanced hydrophilicity, biocompatibility, and crosslinking capability. It is essential for R&D and production in industries requiring high-performance specialty materials, including biomedical engineering, advanced coatings, and personal care.

Application

• Biomedical Polymers: Key monomer for synthesizing hydrogels, contact lenses, drug delivery systems, and tissue engineering scaffolds due to its biocompatibility and ability to form hydrophilic networks.
• Advanced Coatings & Adhesives: Used to produce water-soluble or dispersible resins, improving adhesion, flexibility, and durability in industrial and decorative coatings, inks, and pressure-sensitive adhesives.
• Personal Care & Cosmetics: Serves as a precursor for polymers used in hair styling products, skincare formulations, and nail varnishes, providing film-forming and conditioning properties.
• Chromatography Media: Employed in the manufacture of affinity chromatography supports and HPLC stationary phases for protein separation and purification.
• Photoresists & Electronics: A component in photopolymerizable compositions for microelectronics and printed circuit boards.
• Crosslinking Agent: Functions as a reactive diluent and crosslinker in radiation-curable (UV/EB) systems, enhancing the mechanical and chemical resistance of the final polymer.

Quality Control

Our n-(2-Hydroxyethyl) Methacrylamide is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment to guarantee it meets your specific application requirements.

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). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and away from direct light exposure to maintain stability and prevent polymerization.
