Description

α-Cuparenone is a sesquiterpenoid ketone characterized by its unique cuparene skeleton structure. This compound is valued for its distinct woody, ambergris-like aroma profile, making it a significant material in the creation of sophisticated fragrance compositions. It serves as a key intermediate and building block in the synthesis of complex odorants and flavoring agents. Industries such as fine fragrance, cosmetics, and specialty chemical synthesis utilize this material for its olfactory properties and chemical functionality.

Application

• Fragrance Industry: Used as a base note in premium perfumery to impart woody, ambery, and long-lasting olfactory characteristics.
• Flavoring Agent: Employed as an intermediate in the synthesis of complex flavor molecules for high-end applications.
• Cosmetic Ingredients: Incorporated as a fragrance component in lotions, creams, and other personal care products.
• Chemical Synthesis: Serves as a chiral building block or starting material for the synthesis of other terpenoids and specialty organic compounds.
• Aromatherapy & Home Fragrance: Used in candles, diffusers, and other home scent products for its rich and persistent aroma.
• Research & Development: Utilized in academic and industrial R&D for studying terpenoid chemistry and exploring new olfactory molecules.

Quality Control

Our α-Cuparenone is produced and tested under strict quality management protocols to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques including GC, GC-MS, and NMR for comprehensive identity and purity verification. While this product is typically supplied as a high-grade material for fragrance applications, Certificates of Analysis (COA) detailing specific lot parameters are available upon request to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen) to preserve stability and prevent degradation. Keep away from heat, sparks, and open flame.
