Description

2H-Pyran-2,4-Diol, 2-Ethyltetrahydro-3,5-Dimethyl-6-(1-Methylethyl)-, (2S,3R,4R,5S,6R)- (9Ci) is a high-purity, stereochemically defined dihydropyran derivative that serves as a critical chiral building block and intermediate in advanced organic synthesis. Its precise stereochemistry and functional groups make it invaluable for constructing complex molecular architectures with high enantiomeric purity. This compound is primarily sought by research institutions and industrial R&D departments in the pharmaceutical, agrochemical, and specialty chemical sectors for the development of novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the research and development of new active pharmaceutical ingredients (APIs), particularly in antiviral, anti-inflammatory, or central nervous system (CNS) drug candidates.
• Agrochemical Synthesis: Used as a precursor in the synthesis of novel herbicides, fungicides, or insecticides where specific stereochemistry influences biological activity.
• Asymmetric Catalysis Ligand Precursor: Serves as a starting material for the synthesis of chiral ligands used in asymmetric hydrogenation or other enantioselective catalytic processes.
• Fine Chemical & Flavor/Fragrance Intermediate: Employed in the multi-step synthesis of complex natural product analogs, aroma chemicals, or other high-value specialty compounds.
• Academic & Contract Research: A valuable tool for methodological development in synthetic organic chemistry, enabling studies on stereoselective reactions and total synthesis.
• Material Science Research: Potential monomer or modifier in the development of novel polymers with specific optical or structural properties.
