Description

(S)-1,2-Bis(Diphenylphosphino)Cyclohexylethane is a high-value, chiral bisphosphine ligand crucial for enabling highly selective asymmetric catalytic transformations. Its primary value lies in its ability to induce chirality in transition metal complexes, leading to the production of enantiomerically pure compounds, which are essential in advanced pharmaceutical and fine chemical synthesis. This product is specifically needed by R&D scientists and process chemists in the pharmaceutical, agrochemical, and specialty chemical industries for developing and scaling up enantioselective hydrogenation, cross-coupling, and hydroformylation reactions.

Application

• As a chiral ligand in asymmetric hydrogenation reactions for the synthesis of enantiomerically pure pharmaceutical intermediates.
• Catalyst component for enantioselective cross-coupling reactions (e.g., Suzuki-Miyaura, Heck) in fine chemical manufacturing.
• Use in asymmetric hydroformylation processes to produce chiral aldehydes.
• Key reagent in the development of novel transition metal catalysts for academic and industrial research.
• Facilitates the synthesis of chiral compounds for agrochemical active ingredients.
• Employed in the preparation of specialty materials with specific optical properties.

Quality Control

Our (S)-1,2-Bis(Diphenylphosphino)Cyclohexylethane is manufactured under strict quality protocols to ensure batch-to-batch consistency and high enantiomeric purity, critical for reproducible catalytic performance. Each lot undergoes comprehensive analysis including chiral HPLC, 31P NMR, and 1H NMR to confirm identity, purity, and enantiomeric excess. Certificates of Analysis (COA) with full analytical data are provided and available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at 2-8°C in a cool, dry place. Due to its sensitivity to oxidation, the container should only be opened in a glovebox or under a positive pressure of inert gas.
