Description

Ruthenium, Bis(Eta5-2,3,4-Trimethylpenta-2,4-Dien-1-Yl)- is an organoruthenium complex featuring two η⁵-coordinated trimethylpenta-2,4-dienyl ligands bound to a central ruthenium(II) center. This air-sensitive, highly reactive metallocene derivative serves as a specialized catalyst precursor in advanced homogeneous catalysis and materials science research. It is critically valued by R&D laboratories and specialty chemical manufacturers engaged in asymmetric synthesis, C–H activation, and the development of next-generation ruthenium-based functional materials.

Application

• Homogeneous catalysis for asymmetric allylic alkylation and olefin metathesis
• Precursor for atomic layer deposition (ALD) and chemical vapor deposition (CVD) of ruthenium-containing thin films
• Research reagent in organometallic chemistry for ligand exchange and complexation studies
• Synthesis of ruthenium-based photoredox catalysts for visible-light-driven organic transformations
• Development of single-source precursors for ruthenium oxide nanomaterials
• Model compound for studying electron transfer mechanisms in bimetallic systems

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is verified for identity, purity, and residual solvent content using orthogonal analytical methods including NMR, elemental analysis, and HPLC. Certificates of Analysis (COA) are available upon request, and manufacturing adheres to ISO 9001-certified quality management practices. Specifications meet or exceed ACS Reagent Grade requirements for research-grade organometallic compounds.

Storage

Preserve in a tightly closed container, protected from light. Store under inert atmosphere (argon or nitrogen) at 2–8 °C. Due to its hygroscopic and easily oxidized nature, minimize exposure to ambient air and moisture during handling. Maintain in a cool, dry, well-ventilated area away from incompatible materials such as strong oxidizers, acids, and alkalis.
