Description

4,7-Diazaspiro[2.5]Octane-5,8-Dione,6-Methyl-,(S)-(9Ci) CAS NO 98735-78-5 is a high-purity, chiral spirocyclic compound belonging to the diazaspiro family. This specialized intermediate is of significant value in modern pharmaceutical research and development, particularly for its role in constructing complex molecular architectures. It is primarily sought after by R&D chemists and process development scientists in the pharmaceutical and fine chemical industries for the synthesis of novel active pharmaceutical ingredients (APIs) and other high-value chiral compounds.

Application

• Pharmaceutical Intermediate: A key chiral building block for the synthesis of novel drug candidates, particularly in central nervous system (CNS) and antiviral research.
• Asymmetric Synthesis: Utilized in the construction of complex, stereochemically defined molecules due to its rigid spirocyclic and chiral (S)-configured structure.
• Ligand and Catalyst Development: Serves as a precursor for developing novel chiral ligands and organocatalysts used in enantioselective transformations.
• Chemical Biology Probes: Incorporated into molecular probes for studying enzyme mechanisms and biological pathways.
• Advanced Material Research: Potential monomer or additive in the development of specialty polymers with unique properties.
• Academic Research: Used in university and institutional labs for methodological development and exploring new chemical space in heterocyclic chemistry.
