Description

2-(1-Oxa-4-Azaspiro[4.5]Dec-4-Yl)Ethyl Methacrylate is a specialized methacrylate monomer featuring a spirocyclic amino ether functional group, which imparts unique reactivity and polymer properties. This compound is valued for its ability to introduce polar, hydrophilic, and potentially bioactive characteristics into polymer chains, enhancing adhesion, compatibility, and functionality. It is primarily sought by R&D chemists and formulators in the advanced polymer, specialty coatings, and biomedical materials sectors for developing high-performance acrylic resins and functional copolymers.

Application

• Advanced Polymer Synthesis: Serves as a key monomer for creating specialty acrylic and methacrylic copolymers with tailored properties.
• UV-Curable Coatings & Inks: Incorporated into formulations to improve adhesion to difficult substrates and enhance coating flexibility and durability.
• Biomedical & Hydrogel Materials: Used in the development of contact lenses, drug delivery systems, and biocompatible hydrogels due to its polar and hydrophilic spirocyclic side chain.
• Adhesive & Sealant Formulations: Enhances the bonding strength and environmental resistance of industrial and medical-grade adhesives.
• Ion-Exchange & Chelating Polymers: The amino ether group allows for the creation of polymers with metal-binding capabilities for filtration and purification applications.
• Modifier for Resin Properties: Acts as a functional comonomer to modify the hydrophilicity, glass transition temperature (Tg), and mechanical properties of standard acrylic resins.

Quality Control

Our production of 2-(1-Oxa-4-Azaspiro[4.5]Dec-4-Yl)Ethyl Methacrylate adheres to strict quality management protocols. Each batch is analyzed to ensure high purity and consistency, with critical parameters monitored via GC, HPLC, and NMR. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) or as specified on the label. This product is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). It is recommended to store under an inert gas such as nitrogen or argon and allow the container to reach ambient temperature before opening to prevent moisture condensation.
