Description

Bis[2-(2-Bromoisobutyryloxy)Undecyl] Disulfide 97% is a high-purity, bifunctional organosulfur compound featuring both a disulfide linkage and bromoisobutyrate groups, serving as a specialized polymerization initiator and chain transfer agent. Its molecular architecture is engineered to enable precise control over polymer architecture in advanced material synthesis. This product is essential for researchers and manufacturers in the fields of polymer chemistry and materials science, particularly for developing polymers with tailored properties such as self-healing capabilities, controlled degradation, or specific surface functionalities.

Application

• Reversible Addition-Fragmentation Chain-Transfer (RAFT) Polymerization: Acts as a specialized chain transfer agent (CTA) for the controlled synthesis of polymers with complex architectures like block copolymers and star polymers.
• Atom Transfer Radical Polymerization (ATRP): Functions as a dual-purpose initiator and iniferter due to its bromoisobutyrate groups, facilitating surface-initiated polymerization and the creation of polymer brushes.
• Synthesis of Disulfide-Linked Polymers: Enables the production of polymers with dynamic, redox-responsive disulfide bonds in the backbone for stimuli-responsive drug delivery systems and self-healing materials.
• Surface Modification and Functionalization: Used to graft polymer chains onto nanoparticles, silicon wafers, or other substrates to alter surface properties like wettability, biocompatibility, or adhesion.
• Advanced Material Research: A key building block in R&D for creating novel hydrogels, nanocomposites, and smart materials with precisely controlled molecular weight and dispersity.
• Bioconjugation and Biomedical Applications: Facilitates the controlled attachment of polymers to biomolecules (proteins, peptides) for constructing polymer-drug conjugates or diagnostic agents.

Quality Control

Our Bis[2-(2-Bromoisobutyryloxy)Undecyl] Disulfide 97% is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity for research and production. Each lot undergoes comprehensive analytical testing, including HPLC for purity and NMR for structural confirmation. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key specifications 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 a controlled 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.
