Description

Polyethylene Glycol-Bound Ruthenium Carbene Complex is a specialized, polymer-supported organometallic catalyst designed for enhanced recyclability and handling in synthetic chemistry. This innovative product combines the high catalytic activity of a ruthenium carbene core with the solubility and phase-separation benefits of a polyethylene glycol (PEG) matrix. It is a critical reagent for researchers and process chemists in the pharmaceutical, fine chemical, and advanced materials sectors who require efficient, recoverable catalysts for key transformations like olefin metathesis.

Application

• Ring-Closing Metathesis (RCM): A key catalyst for the efficient synthesis of small, medium, and macrocyclic ring systems, crucial in natural product and pharmaceutical intermediate synthesis.
• Cross-Metathesis (CM): Enables the selective coupling of terminal olefins to build complex molecular architectures for specialty chemicals and polymer precursors.
• Supported & Recyclable Catalysis: The PEG-bound nature allows for facile catalyst recovery and reuse in batch processes, improving cost-efficiency and reducing metal contamination in products.
• Flow Chemistry: Suitable for use in continuous flow reactor systems due to its potential for immobilization, enabling scalable and safer production processes.
• Pharmaceutical Intermediate Synthesis: Used in the development and production of active pharmaceutical ingredients (APIs) requiring metathesis steps under controlled conditions.
• Polymer & Material Science: Facilitates the synthesis of functional polymers and novel materials via acyclic diene metathesis (ADMET) polymerization or polymer modification.

Quality Control

Our Polyethylene Glycol-Bound Ruthenium Carbene Complex is manufactured under strict quality protocols to ensure batch-to-batch consistency and high catalytic performance. Each lot is characterized to confirm identity, ruthenium content, and functional activity. A comprehensive Certificate of Analysis (COA) detailing specifications such as ruthenium assay, ligand loading, and residual solvent levels is provided with every shipment to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C to maintain stability. This material is hygroscopic (moisture-sensitive) and easily oxidized; ensure containers are sealed immediately after use to minimize exposure to air and moisture.
