Description

Humulene Oxide, 1,5,9,9-Tetramethyl-12-Oxabicyclododeca-4,7-Diene is a high-purity sesquiterpene oxide valued for its unique bicyclic structure and aromatic properties. This compound is essential for applications requiring a sophisticated, woody, and amber-like olfactory profile. It is primarily sought after by manufacturers in the fragrance, flavor, and advanced chemical synthesis industries for creating complex scent accords and as a key chiral intermediate.

Application

• Fragrance & Perfumery: A key ingredient in high-end perfumes, colognes, and personal care products, contributing woody, amber, and earthy base notes.
• Flavoring Agent: Used in the creation of complex flavor profiles for premium food and beverage products, adding subtle woody and spicy nuances.
• Aromatherapy & Essential Oils: Incorporated into therapeutic blends and natural oil formulations for its grounding and distinctive aromatic character.
• Chemical Synthesis: Serves as a valuable chiral building block or intermediate in the synthesis of more complex terpenoids and fine chemicals.
• Cosmetic Formulations: Used as a fragrance component in lotions, creams, and soaps to provide a long-lasting, natural scent.
• Research & Development: Utilized in academic and industrial R&D for studying terpene chemistry, olfactory receptors, and natural product synthesis.
