Description

(S)-Daipen CAS NO 148369-91-9 is a high-purity chiral ligand and catalyst precursor, specifically the (S)-enantiomer of 1,1'-bis(diphenylphosphino)ferrocene. This compound matters for its critical role in facilitating highly enantioselective transformations, enabling the production of single-isomer pharmaceutical intermediates and fine chemicals with superior optical purity. Industries that require precise stereochemical control, such as pharmaceutical R&D, asymmetric catalysis, and advanced material synthesis, rely on this high-performance ligand for its proven efficacy and reliability.

Application

• As a key chiral ligand in asymmetric hydrogenation reactions for pharmaceutical active ingredient (API) synthesis.
• Catalyst precursor for enantioselective carbon-carbon bond formation (e.g., cross-coupling, allylic substitution).
• Critical component in the synthesis of chiral ferrocenylphosphines for advanced catalytic systems.
• Used in academic and industrial R&D for developing new asymmetric synthetic methodologies.
• Employed in the production of optically pure agrochemicals and flavor & fragrance compounds.
• Facilitates stereoselective polymerization processes for creating polymers with specific tacticity.

Quality Control

Our (S)-Daipen is manufactured under strict quality management systems to ensure batch-to-batch consistency and high enantiomeric excess. Each lot undergoes comprehensive analytical testing, including HPLC for purity and chiral assay, NMR for structural confirmation, and elemental analysis. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at room temperature (15-25°C). Due to its sensitivity to oxidation, the container should be purged with inert gas after each opening to maintain product integrity.
