Description

(S)-1-{(S)-2-[2-[Di(3,5-Xylyl)Phosphino]Phenyl]Ferrocenyl}Ethyldi(3,5-Xylyl)Phos is a highly specialized, chiral ferrocenyl phosphine ligand, a critical component in asymmetric catalysis. Its value lies in its ability to induce high enantioselectivity in transition metal-catalyzed reactions, which is essential for producing single-enantiomer compounds. This ligand is primarily needed by research institutions and pharmaceutical manufacturers engaged in the development of chiral active pharmaceutical ingredients (APIs), fine chemicals, and advanced materials.

Application

• As a chiral ligand in asymmetric hydrogenation reactions for pharmaceutical intermediate synthesis.
• Catalyst component for asymmetric C-C bond formation (e.g., cross-coupling, allylic substitution).
• Enantioselective synthesis of flavors, fragrances, and agrochemicals requiring specific stereochemistry.
• Key reagent in academic and industrial R&D for developing new catalytic methodologies.
• Production of optically pure fine chemicals and advanced organic materials.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized using advanced analytical techniques to confirm identity, purity, and chiral integrity. Certificates of Analysis (COA) detailing specifications such as chiral purity (enantiomeric excess) and chemical assay are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) to prevent oxidation and degradation. Keep the container in a dry, cool, and well-ventilated area.
