Description

(R)-Sunphos is a chiral phosphine ligand with the CAS registry number 765312-57-0, widely recognized for its utility in asymmetric catalysis. This compound matters because it enables highly enantioselective transformations, a critical requirement for producing single-isomer pharmaceuticals and fine chemicals. Industries that need it include pharmaceutical R&D, agrochemical manufacturing, and advanced material synthesis, where precise stereochemical control is paramount.

Application

• As a chiral ligand in asymmetric hydrogenation reactions for pharmaceutical intermediates.
• Catalyst component in enantioselective C-C and C-X bond-forming cross-coupling reactions.
• Key reagent for the synthesis of chiral active pharmaceutical ingredients (APIs).
• Use in the development of novel agrochemicals requiring specific stereochemistry.
• Research and development of new catalytic systems in academic and industrial laboratories.
• Production of specialty chemicals and advanced materials with defined chiral properties.

Quality Control

Our (R)-Sunphos is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including chiral purity assessment by HPLC, to meet the exacting standards required for asymmetric synthesis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and chiral excess is provided with every shipment.

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) in a cool, dry, and well-ventilated area. This material is easily oxidized and light-sensitive; prolonged exposure to air or light should be avoided to maintain stability and efficacy.
