Description

(-)-2,3-Bis((2S,5S)-2,5-Diethylphospholano)Benzo[B]Thiophene(1,5-Cyclooctadiene)Rhodium(I)Tetrafluoroborate is a highly specialized, chiral transition metal complex designed for asymmetric catalysis. This compound matters because it serves as a precise and efficient catalyst for enantioselective hydrogenation and other critical synthetic transformations, enabling the production of single-isomer intermediates. It is essential for R&D chemists and process engineers in the pharmaceutical, agrochemical, and fine chemical industries who require high enantiomeric purity and consistent catalytic performance.

Application

• Asymmetric Hydrogenation Catalyst: Key for the enantioselective synthesis of chiral amines, amino acids, and other pharmaceutical building blocks.
• Pharmaceutical Intermediate Synthesis: Enables the production of active pharmaceutical ingredients (APIs) with high optical purity.
• Agrochemical Manufacturing: Used in the synthesis of chiral herbicides, fungicides, and plant growth regulators.
• Fine Chemical Production: Facilitates the creation of specialty chemicals, flavors, and fragrances requiring specific stereochemistry.
• Academic and Industrial R&D: A valuable tool for method development and exploring new catalytic asymmetric reactions.
• Process Chemistry Optimization: Employed in scaling up laboratory syntheses to commercial manufacturing processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a freezer at -20°C to -10°C under an inert atmosphere (e.g., argon or nitrogen) due to its moisture-sensitive and light-sensitive nature. Allow the sealed container to equilibrate to room temperature before opening to prevent condensation and moisture ingress.
