Description

(S)-3,7-Dimethyloct-7-Enyl Isovalerate CAS NO 7778-96-3 is a chiral ester compound, specifically the (S)-enantiomer of a terpene-derived fragrance intermediate. This compound matters for its role as a high-value building block in the synthesis of complex, optically active aroma chemicals and pharmaceutical intermediates. It is primarily needed by manufacturers in the flavors and fragrances (F&F) industry, as well as by fine chemical producers developing chiral active ingredients.

Application

• Fragrance Ingredient Synthesis: A key chiral intermediate for creating sophisticated, high-impact aroma molecules with specific olfactory profiles.
• Flavor Compound Production: Used in the synthesis of natural-identical or artificial flavoring agents, particularly those requiring specific stereochemistry for authentic taste.
• Fine Chemical Intermediate: Serves as a chiral synthon in the multi-step synthesis of complex molecules for pharmaceutical and agrochemical research.
• Perfumery Compounds: Incorporated into the formulation of premium perfumes, colognes, and personal care products to impart unique, long-lasting scent characteristics.
• Chemical Research & Development: Utilized in academic and industrial R&D for studying stereoselective reactions and developing new synthetic methodologies.
• Specialty Additives: Potential use in the development of specialty additives where a specific terpene ester structure is required.
