Description

1,3-Benzoxaphosphole, 4-(9-Anthracenyl)-3-(1,1-dimethylethyl)-2-ethyl-2,3-dihydro-, (2R,3R)- is a high-purity, stereochemically defined organophosphorus compound featuring an anthracene moiety. This specific chiral structure makes it a valuable advanced intermediate or ligand for sophisticated chemical synthesis, particularly in the development of novel materials and pharmaceuticals. It is primarily sought by R&D chemists and process development scientists in fine chemical, pharmaceutical, and advanced material sectors for applications requiring precise molecular architecture.

Application

• Pharmaceutical Intermediate: Serves as a key chiral building block in the synthesis of potential active pharmaceutical ingredients (APIs), especially for target-oriented drug discovery programs.
• Catalyst Ligand Development: Utilized in the research and development of novel chiral ligands for asymmetric catalysis, leveraging its rigid, bulky anthracenyl and tert-butyl groups.
• Advanced Material Research: Acts as a precursor for functional organic materials, such as organic light-emitting diodes (OLEDs) or photoresponsive polymers, due to the anthracene chromophore.
• Chemical Biology Probes: Employed in the design of molecular probes to study biological processes, where its fluorescence and specific stereochemistry can be exploited.
• Academic & Industrial R&D: Used in research laboratories for methodological studies in organic synthesis and the exploration of new chemical spaces.
