Description

2H-Pyran-3,4-Dione, Dihydro-5-Hydroxy-6-Methoxy-, (5S,6R)- (9Ci) is a high-purity, stereochemically defined heterocyclic compound that serves as a critical chiral building block and synthetic intermediate. Its unique pyran-dione core with specific stereochemistry makes it valuable for constructing complex molecular architectures with precise biological activity. This compound is primarily sought by research and development teams in the pharmaceutical, agrochemical, and fine chemical industries for applications in asymmetric synthesis and the development of novel active ingredients.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of new drug candidates, particularly those targeting specific enzymatic pathways.
• Agrochemical Synthesis: Used in the development of advanced, stereoselective pesticides and herbicides where the specific (5S,6R) configuration is crucial for bioactivity.
• Fine Chemical Production: Serves as a specialized building block for synthesizing complex flavors, fragrances, and functional materials requiring high stereochemical purity.
• Academic & Contract Research: An essential reagent for methodological studies in organic chemistry, catalysis, and total synthesis of natural products.
• Biochemical Research: Potential use as a precursor or analog in studying enzyme inhibitors or modulators due to its dihydroxy-methoxy substitution pattern.
