Description

(R,R)-N,N'-Bis(Trifluoromethanesulfonyl)-1,2-Diphenylethylenediamine is a high-purity, chiral sulfonamide derivative that serves as a critical ligand and catalyst precursor in advanced asymmetric synthesis. Its value lies in enabling highly enantioselective transformations, which are essential for producing single-isomer active pharmaceutical ingredients (APIs) and fine chemicals. This compound is primarily needed by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors for developing novel chiral compounds and process optimization.

Application

• As a chiral ligand for transition metal catalysts in asymmetric hydrogenation and carbon-carbon bond-forming reactions.
• As a key intermediate or catalyst precursor in the synthesis of enantiomerically pure pharmaceutical actives.
• For use in academic and industrial R&D focused on developing new asymmetric catalytic methodologies.
• In the preparation of high-value specialty chemicals and agrochemical intermediates requiring specific chirality.
• As a standard or reference material for analytical method development in chiral separation techniques (e.g., HPLC, SFC).
• For scale-up process development in contract manufacturing organizations (CMOs) serving the pharma and biotech industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect performance. For long-term storage, consider using desiccants.
