Description

1S,2S-N,N'-Bis(Phenylmethyl)-1,2-Diphenyl-1,2-Ethanediamine is a high-purity chiral diamine ligand of significant interest in advanced organic synthesis. Its core value lies in its ability to act as a highly effective and selective catalyst or chiral auxiliary in asymmetric transformations, enabling the production of enantiomerically pure compounds. This product is essential for research and development laboratories, as well as production facilities in the pharmaceutical, agrochemical, and fine chemical industries, where precise stereochemical control is paramount.

Application

• Asymmetric Catalysis: As a key chiral ligand for transition metal catalysts (e.g., with Ru, Rh, Ir) in hydrogenation, hydrosilylation, and other enantioselective reactions.
• Pharmaceutical Intermediate Synthesis: For the production of chiral active pharmaceutical ingredients (APIs) requiring high enantiomeric excess (ee).
• Agrochemical Manufacturing: In the synthesis of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Fine Chemical Production: Used in the preparation of specialty chemicals, flavors, and fragrances where stereochemistry is critical.
• Academic & Industrial R&D: A valuable tool for method development and exploring new asymmetric synthetic pathways.
• Chiral Resolution Agent: Potentially used in the separation of racemic mixtures.

Quality Control

Our 1S,2S-N,N'-Bis(Phenylmethyl)-1,2-Diphenyl-1,2-Ethanediamine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC, to ensure compliance with stringent specifications for research and industrial use. Certificates of Analysis (COA) detailing identity, purity (assay), enantiomeric excess, and related substances are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to exclude moisture. For long-term storage, consider storing under an inert atmosphere.
