Description

1,1''-(1,2-Phenylene)-Bis-[2,5-Dimethyl-(2S,2''S,3S,3''S,4S,4''S,5S,5''S)-3,4-Phospholanediol-(1,5-Cyclooctadiene)-Rhodium(I)]-Tetrafluoroborate is a highly specialized, chiral organorhodium complex designed for asymmetric catalysis. This compound matters because it serves as a precise and efficient catalyst for enantioselective hydrogenation and other critical C-C bond-forming reactions, enabling the production of single-isomer intermediates. It is essential for advanced research and manufacturing in the pharmaceutical, agrochemical, and fine chemical industries, where controlling stereochemistry is paramount for product efficacy and safety.

Application

• Asymmetric Hydrogenation Catalyst: For the enantioselective reduction of prochiral olefins, ketones, and imines in pharmaceutical intermediate synthesis.
• Chiral Ligand Complex: As a pre-formed catalyst for C-C and C-H bond activation reactions in fine chemical production.
• Pharmaceutical Intermediate Synthesis: Production of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity, such as chiral amines and amino acid derivatives.
• Agrochemical Manufacturing: Synthesis of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Academic & Industrial R&D: A key reagent for method development and exploration of new asymmetric catalytic transformations.
• Specialty Polymer Synthesis: Catalyzing stereoregular polymerization for advanced materials with specific optical or mechanical properties.

Quality Control

Our high-value organometallic catalysts are produced and handled under strict quality-controlled, inert atmosphere conditions to ensure batch-to-batch consistency and catalytic activity. Each lot undergoes comprehensive analysis, including HPLC for purity, NMR for structural confirmation, and chiral analysis to verify enantiomeric integrity. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key specifications relevant to catalytic performance.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at 2-8°C to maintain stability and prevent decomposition. This material is light-sensitive and easily oxidized; prolonged exposure to air, moisture, or elevated temperatures should be avoided.
