Description

(S)-(-)-δ-Decanolactone CAS NO 59285-67-5 is a high-purity, optically active lactone compound valued for its distinctive flavor and fragrance profile. This chiral intermediate is essential for synthesizing complex molecules where stereochemistry is critical to function and sensory properties. It is primarily sought after by manufacturers in the flavor & fragrance, pharmaceutical, and fine chemical industries for creating premium, enantiomerically pure products.

Application

• Flavor & Fragrance Ingredient: Key chiral building block for synthesizing natural-tasting fruit flavors (e.g., peach, coconut, dairy) and sophisticated fragrance compounds.
• Pharmaceutical Intermediate: Used in the asymmetric synthesis of active pharmaceutical ingredients (APIs) and other bioactive molecules requiring specific stereochemistry.
• Fine Chemical Synthesis: Serves as a versatile chiral synthon for producing specialty chemicals, liquid crystals, and advanced polymeric materials.
• Research & Development: A valuable reference standard and starting material in academic and industrial R&D for exploring new synthetic methodologies.
• Natural Product Synthesis: Employed in the total synthesis of complex natural products that contain lactone or chiral aliphatic chain motifs.
