Description

(S)-(+)-[(S)-2-Diphenylphosphinoferrocenyl] (N,n-Dimethylamino) (2-Diphenylphosphinophenyl)Methane, Min. 97% Taniaphos is a high-purity, chiral ferrocenyl diphosphine ligand widely recognized for its exceptional performance in asymmetric catalysis. Its primary value lies in enabling highly enantioselective transformations, which are critical for producing single-enantiomer intermediates in fine chemical and pharmaceutical synthesis. This product is essential for research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-performance ligands for hydrogenation, cross-coupling, and other transition metal-catalyzed reactions.

Application

Taniaphos is a premier ligand for a wide range of asymmetric catalytic processes. Its applications include, but are not limited to:

• Asymmetric Hydrogenation of olefins, ketones, and imines for the production of chiral alcohols and amines.
• Enantioselective Cross-Coupling Reactions, such as Suzuki-Miyaura and Buchwald-Hartwig aminations.
• Pharmaceutical Intermediate Synthesis, crucial for creating active pharmaceutical ingredients (APIs) with high optical purity.
• Agrochemical Research, for the development of enantiomerically pure herbicides, fungicides, and pesticides.
• Academic and Industrial R&D in novel catalytic methodologies and ligand design.
• Process Chemistry Optimization for scaling up asymmetric transformations from lab to pilot plant.

Quality Control

Our Taniaphos ligand is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high catalytic performance. Each lot is characterized by NMR (1H, 31P), HPLC, and elemental analysis to confirm identity, purity (>97%), and enantiomeric excess. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment. Our quality system is designed to meet the stringent requirements of GMP and ISO standards for advanced chemical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at 2-8°C in a dry, cool place. Due to its sensitivity to oxidation and moisture, the container should only be opened in a controlled, dry environment and resealed immediately after use. For long-term storage, keep the primary container inside a sealed secondary container with desiccant.
