Description

α-Acoradiene is a naturally occurring sesquiterpene hydrocarbon, a key component of the essential oil derived from the heartwood of the Japanese cedar (*Cryptomeria japonica*). This compound is valued for its distinctive woody, cedar-like aroma and its role as a chemical intermediate in the synthesis of more complex fragrance molecules. It is primarily sought after by manufacturers in the fragrance, flavor, and specialty chemical industries for creating authentic woody and amber scent profiles. Its unique structure also makes it a compound of interest in academic and industrial research for exploring new synthetic pathways and biological activities.

Application

• Fragrance & Perfumery: A key ingredient for imparting warm, woody, and earthy base notes in fine perfumes, colognes, and personal care products.
• Flavor Enhancement: Used in trace amounts to add subtle woody or balsamic nuances to specialty food and beverage flavorings.
• Aromatherapy & Home Fragrance: Incorporated into essential oil blends, candles, and diffusers for its grounding, natural cedarwood scent.
• Chemical Synthesis: Serves as a valuable chiral building block and intermediate in the organic synthesis of novel sesquiterpenoids and fragrance chemicals.
• Research & Development: Used as a reference standard in analytical chemistry (GC, GC-MS) and for studying the biological properties of sesquiterpenes.

Quality Control

Our α-Acoradiene is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and purity. Each lot is analyzed using advanced chromatographic techniques (GC, GC-MS) to confirm identity and quantify major components. A comprehensive Certificate of Analysis (COA) detailing purity, specific rotation (where applicable), and chromatographic profile is provided with every shipment. We adhere to relevant industry standards for aroma chemicals and can support compliance documentation as required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). This material is light-sensitive and easily oxidized; for long-term storage, consider filling the headspace with an inert gas (e.g., nitrogen or argon) to maintain stability and prevent degradation.
