Description

Ethanone, 1-[4,5-Dihydro-2-Methyl-5-(1-Propenyl)-3-Furanyl]-, [R-(E)]- (9Ci) is a high-purity, optically active furanone derivative with a distinct stereochemistry. This compound is valued for its role as a key chiral intermediate and flavor/fragrance precursor in advanced chemical synthesis. It is primarily sought by R&D and production teams in the pharmaceutical, flavor & fragrance (F&F), and fine chemical industries for creating complex, high-value target molecules.

Application

• Pharmaceutical Intermediate: Serves as a critical chiral building block for the synthesis of active pharmaceutical ingredients (APIs), particularly in projects requiring specific stereochemical control.
• Flavor & Fragrance Ingredient: Acts as a precursor for creating sophisticated, natural-identical flavor compounds and aroma chemicals with unique sensory profiles.
• Agrochemical Synthesis: Used in the research and development of novel, optically active agrochemicals and pesticides.
• Organic Synthesis Research: Employed in academic and industrial laboratories for methodological development in asymmetric synthesis and heterocyclic chemistry.
• Fine Chemical Production: Integral to the multi-step synthesis of specialty chemicals where its specific furanone structure imparts desired functional properties.

Quality Control

Our production of this chiral intermediate adheres to strict quality protocols to ensure batch-to-batch consistency and high enantiomeric purity. Each lot is characterized using advanced analytical techniques including chiral HPLC, GC, and NMR to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing assay, enantiomeric excess (ee), and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its highly volatile nature, ensure containers are securely sealed when not in use and stored away from heat and ignition sources.
