Description

(-)-2-Cedranone is a high-purity, optically active sesquiterpenoid ketone valued for its unique and complex woody-amber olfactory profile. This compound matters to industries requiring sophisticated, natural-smelling fragrance components with specific stereochemistry for premium product formulations. It is primarily needed by manufacturers in the fragrance and flavor industry, as well as by research institutions developing novel aroma chemicals or studying olfactory receptors.

Application

• Premium Fragrance Formulations: Serves as a key intermediate or base note in high-end perfumes, colognes, and personal care products, imparting rich woody, ambery, and slightly animalic nuances.
• Flavor Enhancers: Used in trace amounts to create complex, natural woody or earthy flavor profiles in specialty food and beverage applications.
• Aroma Chemical Synthesis: Acts as a critical chiral building block for the synthesis of other valuable fragrance molecules like cedrol derivatives and other sesquiterpenoids.
• Fine Chemical Research: Employed in academic and industrial R&D for studying structure-odor relationships, chiral recognition in olfaction, and natural product synthesis.
• Functional Perfumery: Incorporated into air fresheners, detergents, and household products to provide long-lasting, sophisticated scent profiles.

Quality Control

Our (-)-2-Cedranone is produced under strict quality management systems to ensure batch-to-batch consistency and high optical purity. Each lot is analyzed using advanced chromatographic and spectroscopic techniques. A comprehensive Certificate of Analysis (COA) detailing assay, enantiomeric excess, and impurity profiles is provided with every shipment to guarantee it meets the stringent requirements of the fragrance and research industries.

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). Keep away from strong oxidizing agents and heat sources. For long-term storage, consider an inert atmosphere to preserve organoleptic properties.
