Description

n-[(1R,2R)-2-Amino-1,2-Diphenylethyl]-Benzenesulfonamide is a high-purity chiral sulfonamide derivative, serving as a critical building block and chiral auxiliary in advanced organic synthesis. Its value lies in its ability to impart stereoselectivity in complex chemical transformations, enabling the production of enantiomerically pure compounds. This product is essential for research and development chemists in the pharmaceutical, agrochemical, and fine chemical industries who require reliable, high-quality chiral intermediates for asymmetric synthesis and catalyst development.

Application

• Pharmaceutical Intermediate: A key chiral precursor in the synthesis of active pharmaceutical ingredients (APIs) requiring specific stereochemistry.
• Chiral Auxiliary: Used to control stereoselectivity in asymmetric synthesis, including aldol reactions, alkylations, and Diels-Alder reactions.
• Catalyst Ligand Precursor: Serves as a starting material for the development of novel chiral ligands used in metal-catalyzed reactions.
• Fine Chemical Synthesis: Employed in the research and production of specialty chemicals, flavors, and fragrances where enantiopurity is critical.
• Agrochemical Research: Used in developing enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Academic & Industrial R&D: A valuable tool for methodological development in organic chemistry and process chemistry optimization.

Quality Control

Our n-[(1R,2R)-2-Amino-1,2-Diphenylethyl]-Benzenesulfonamide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and enantiomeric excess meet stringent specifications. Certificates of Analysis (COA) with detailed chromatographic data (HPLC, Chiral HPLC) are provided for every shipment, ensuring full traceability and compliance with cGMP standards where applicable.

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 to exclude moisture. For long-term storage, consider using desiccants or storing under an inert atmosphere.
