Description

Dinaphtho[2,1-D:1',2'-F][1,3,2]Dioxaphosphepin-4-Amine, 2,6-Dibromo-N,n-Bis[(1R)-1-Phenylethyl]-, (11Bs)- (9Ci) is a sophisticated chiral organophosphorus compound featuring a dibrominated dinaphthodioxaphosphepin core. This molecule is of significant value as a highly specialized ligand or catalyst precursor in asymmetric synthesis, where its rigid, sterically demanding structure enables precise stereochemical control. It is primarily required by pharmaceutical R&D laboratories and fine chemical manufacturers developing novel active ingredients and advanced materials.

Application

• Asymmetric Catalysis: Serving as a chiral ligand or precursor for transition metal catalysts in enantioselective C-C and C-X bond-forming reactions.
• Pharmaceutical Intermediate Synthesis: A key building block in the research and development of novel, stereochemically complex drug candidates.
• Advanced Material Research: Potential use in the development of chiral polymers or frameworks with specific optical or electronic properties.
• Methodology Development: Employed by academic and industrial chemists to explore new catalytic transformations and synthetic pathways.
• Process Chemistry Optimization: Used to develop and scale up efficient, stereoselective manufacturing routes for high-value fine chemicals.

Quality Control

Every batch of our chiral organophosphorus compounds is produced and tested under strict quality management protocols. We employ advanced analytical techniques including HPLC, NMR, and chiral analysis to ensure identity, purity, and enantiomeric excess meet exacting standards. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee traceability and support your regulatory and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C in a dry, cool environment to prevent oxidation and moisture absorption. Allow the sealed container to reach room temperature before opening to minimize condensation.
