Description

1-Benzyl-3-{(1R,2R)-2-[(11Bs)-Dinaphtho[2,1-D:1',2'-F][1,3,2]Dioxaphosphepin-4-Ylamino]Cyclohexyl}Urea, Min. 97% is a high-purity, chiral organophosphorus compound featuring a complex, sterically defined structure. This compound is of significant value as a sophisticated ligand or chiral auxiliary in asymmetric synthesis and catalysis, enabling the production of enantiomerically pure intermediates. It is primarily needed by research institutions and pharmaceutical companies engaged in the development of novel active pharmaceutical ingredients (APIs) and advanced materials.

Application

• As a chiral ligand in transition metal-catalyzed asymmetric reactions, such as hydrogenation, hydroformylation, or cross-coupling.
• As a key building block or intermediate in the multi-step synthesis of complex pharmaceutical candidates and fine chemicals.
• For use in academic and industrial research exploring new methodologies in stereoselective synthesis.
• Potential application in the development of advanced materials where chiral induction is required.
• As a reference standard for analytical method development and quality control in chiral separation techniques.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is analyzed to confirm identity, purity, and chiral integrity. Certificates of Analysis (COA) documenting comprehensive testing results, including chiral HPLC purity, are available upon request. We adhere to strict internal quality management protocols to ensure batch-to-batch consistency for research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) for long-term storage or after opening to maintain stability and purity.
