Description

1,4-Cineole is a monoterpene oxide, a key isomer of the more common 1,8-cineole (eucalyptol), distinguished by the position of its oxygen bridge. This compound matters for its unique aromatic profile and chemical reactivity, offering a distinct olfactory character and serving as a valuable intermediate in fine chemical synthesis. It is needed by manufacturers in the flavor and fragrance industry seeking novel notes, as well as by research and development laboratories focused on terpene chemistry and pharmaceutical intermediates.

Application

• Flavor & Fragrance (F&F) Ingredient: Used as a building block or modifier to create unique minty, camphoraceous, and herbal aromatic profiles in perfumes, cosmetics, and air fresheners.
• Pharmaceutical Intermediate: Serves as a chiral starting material or precursor in the synthesis of more complex bioactive molecules and active pharmaceutical ingredients (APIs).
• Research & Development: Employed as a standard or reagent in organic synthesis, catalysis studies, and structure-activity relationship (SAR) research within academic and industrial labs.
• Industrial Aromatics: Incorporated into technical-grade formulations for industrial deodorants, cleaning agents, and functional solvents where specific olfactory characteristics are required.

Quality Control

Our 1,4-Cineole is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing including GC, IR, and NMR to verify identity and purity, ensuring it meets the specifications required for your application. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

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 and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize headspace after partial use.
