Description

(-)-Fenchone is a naturally occurring bicyclic monoterpene ketone, recognized for its characteristic camphoraceous and earthy aroma. This high-purity enantiomer is a critical chiral building block and flavor/fragrance ingredient, valued for its defined stereochemistry and consistent organoleptic profile. It is essential for manufacturers in the flavor & fragrance, pharmaceutical, and fine chemical synthesis industries seeking reliable, high-quality raw materials.

Application

• Flavor & Fragrance Industry: A key aromatic component used in the formulation of perfumes, soaps, detergents, and air fresheners for its woody, camphor-like notes.
• Pharmaceutical Intermediates: Serves as a chiral synthon in the asymmetric synthesis of more complex bioactive molecules and active pharmaceutical ingredients (APIs).
• Fine Chemical Synthesis: Utilized as a starting material or intermediate in organic synthesis for research and development of novel compounds.
• Food & Beverage: Employed as a flavoring agent (where compliant) to impart earthy, herbal nuances to food products and beverages.
• Agrochemicals: Investigated for use in the synthesis of specialty agrochemicals and as a component in botanical insect repellents.
• Research & Development: A standard compound for analytical testing, method development, and biochemical research in academic and industrial laboratories.

Quality Control

Our (-)-Fenchone is produced and tested under a strict quality management system. Each batch is analyzed to ensure it meets stringent specifications for identity, purity, and enantiomeric excess. A comprehensive Certificate of Analysis (COA) detailing results for assay, optical rotation, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at controlled room temperature (15-25°C). Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and potential changes in concentration.
