Description

(-)-2,3-Dihydro-5,7-Dihydroxy-2-Methyl-4-Quinolone is a chiral, dihydroxy-substituted quinolone derivative that serves as a valuable synthetic intermediate and a potential pharmacophore. Its unique stereochemistry and functional group arrangement make it a critical building block for the development of novel bioactive compounds. This high-purity intermediate is essential for research and production in advanced pharmaceutical synthesis and fine chemical manufacturing.

Application

• Pharmaceutical Intermediate: Key chiral building block for the synthesis of potential drug candidates, particularly in antimicrobial and central nervous system (CNS) therapeutic areas.
• Organic Synthesis Research: Used in academic and industrial R&D for constructing complex heterocyclic compounds and exploring structure-activity relationships (SAR).
• Fine Chemical Production: Serves as a precursor in the manufacture of specialty chemicals, dyes, and advanced materials requiring specific stereochemistry.
• Biochemical Tool Compound: Potential use as a probe or inhibitor in enzymatic studies due to its quinolone core structure.
