Description

2-(2-Bromoisobutyryloxy)Ethyl Methacrylate is a specialized bifunctional monomer featuring both a polymerizable methacrylate group and an atom transfer radical polymerization (ATRP) initiator moiety. This compound matters as a critical building block for synthesizing well-defined polymers with complex architectures, such as block copolymers, star polymers, and polymer brushes. It is essential for researchers and manufacturers in advanced materials science, particularly those developing functional coatings, thermoplastic elastomers, drug delivery systems, and surface-modified nanoparticles.

Application

• ATRP Macroinitiator: Primary use as a versatile initiator for grafting polymers from surfaces or other polymer backbones via Atom Transfer Radical Polymerization.
• Block Copolymer Synthesis: Key monomer for creating precisely controlled block copolymers with tailored properties for adhesives, compatibilizers, and nanostructured materials.
• Surface Modification: Used to create polymer brushes on silicon, gold, or polymer substrates to alter surface characteristics like wettability, friction, and biocompatibility.
• Functional Hydrogels & Networks: Incorporated into cross-linked networks to introduce degradable or responsive units for biomedical and sensor applications.
• Advanced Coatings: Enables the synthesis of coatings with specific mechanical, chemical, or anti-fouling properties.
• Nanoparticle Functionalization: Facilitates the controlled growth of polymer shells on nanoparticles for stabilization and targeted functionality.
• Telechelic Polymers: Serves as an inimer (initiator-monomer) for preparing α-functionalized polymers with reactive end-groups.

Quality Control

Our 2-(2-Bromoisobutyryloxy)Ethyl Methacrylate is produced under strict quality protocols to ensure high purity and batch-to-batch consistency, critical for controlled polymerization reactions. Each lot undergoes comprehensive analysis including NMR, HPLC, and GC to confirm identity, assay, and impurity profiles. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We adhere to a quality management system and can supply material suitable for research and development under cGMP guidelines where required.

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 maintain stability and inhibit premature polymerization. The product is light-sensitive (store away from light) and should be handled in a compatible environment away from strong acids and organic solvents. Allow the container to reach ambient temperature before opening to prevent moisture condensation.
