Description

[1,3-Bis(2,6-Di-I-Propylphenyl)Imidazolidin-2-Ylidene]{2-[[1-(Methoxy(Methyl)Amino)-1-Oxopropan-2-Yl]Oxy]Benzylidene}Ruthenium(II) Dichloride Greencat is a highly specialized, second-generation Grubbs-Hoveyda type olefin metathesis catalyst. This compound matters for its exceptional activity and selectivity in challenging cross-metathesis and ring-closing metathesis (RCM) reactions, enabling the efficient synthesis of complex organic molecules. It is critically needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced materials industries for developing new active ingredients and high-performance polymers.

Application

• Pharmaceutical Intermediate Synthesis: Key for constructing complex macrocyclic and heterocyclic ring systems in active pharmaceutical ingredients (APIs) via ring-closing metathesis (RCM).
• Agrochemical Development: Used in the synthesis of novel, biologically active molecules for crop protection and pest management.
• Advanced Polymer & Material Science: Enables the production of specialty polymers with tailored properties through ring-opening metathesis polymerization (ROMP) and acyclic diene metathesis (ADMET).
• Fine Chemical & Fragrance Manufacturing: Facilitates the efficient and selective formation of carbon-carbon double bonds in the synthesis of high-value flavor and fragrance compounds.
• Academic & Industrial R&D: An essential tool for methodological development in organic synthesis and catalysis research.
• Process Chemistry Optimization: Employed for scaling up metathesis reactions from lab to pilot plant due to its improved stability and functional group tolerance.

Quality Control

Our [1,3-Bis(2,6-Di-I-Propylphenyl)Imidazolidin-2-Ylidene]{2-[[1-(Methoxy(Methyl)Amino)-1-Oxopropan-2-Yl]Oxy]Benzylidene}Ruthenium(II) Dichloride Greencat is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to ensure identity, purity, and catalytic performance. Certificates of Analysis (COA) with detailed specifications are provided to guarantee consistent batch-to-batch quality and support your regulatory and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., argon or nitrogen) at 2-8°C to maintain stability and prevent decomposition. This material is easily oxidized and light-sensitive. Allow the sealed container to reach room temperature before opening to minimize moisture condensation.
