Description

2-Hydroxyethyl α-Bromoisobutyrate is a specialized bifunctional monomer featuring both a polymerizable vinyl group and an initiating site for controlled radical polymerization. This compound matters as a critical ATRP (Atom Transfer Radical Polymerization) initiator and a versatile macromonomer, enabling the precise synthesis of complex polymer architectures with controlled molecular weight and functionality. It is essential for researchers and manufacturers in the polymer industry developing advanced materials such as block copolymers, star polymers, and surface-grafted polymer brushes for applications in coatings, adhesives, and biomedical devices.

Application

• ATRP Initiator: Serves as a key starting material for controlled/living radical polymerization to produce polymers with narrow molecular weight distributions.
• Macromonomer Synthesis: Used to create functional oligomers or polymers with a polymerizable end-group for further copolymerization.
• Surface Modification: Enables the grafting of polymer brushes from surfaces (e.g., silicon, gold, polymers) for creating smart, responsive, or biocompatible coatings.
• Block Copolymer Production: Facilitates the synthesis of well-defined block copolymers for use as thermoplastic elastomers, compatibilizers, or nanostructured materials.
• Star Polymer & Network Formation: Acts as a building block for synthesizing multi-arm star polymers and cross-linked polymer networks.
• Bioconjugation & Drug Delivery: Used in the development of polymer-drug conjugates and functional carriers for targeted delivery systems.
• Advanced Material Research: Fundamental reagent in academic and industrial R&D for exploring new polymer topologies and functionalities.

Quality Control

Our 2-Hydroxyethyl α-Bromoisobutyrate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the high standards required for polymer synthesis and research. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request 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 place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
