Description

1-(2,3,4,7,8,8A-Hexahydro-3,6,8,8-Tetramethyl-1H-3A,7-Methanoazulen-5-Yl)Ethan-1-One is a high-purity synthetic intermediate and fragrance ingredient belonging to the complex sesquiterpenoid chemical class. This compound matters for its role as a key building block in the synthesis of sophisticated aroma chemicals and for imparting unique woody, ambergris-like olfactory characteristics. It is primarily needed by manufacturers in the flavors and fragrances (F&F) industry, as well as by research and development laboratories working on fine chemical synthesis and novel odorant discovery.

Application

• Fragrance Formulation: Serves as a valuable base note and fixative in premium perfumery, contributing to complex woody, amber, and animalic accords.
• Aroma Chemical Synthesis: Acts as a crucial synthetic intermediate for the production of more complex sesquiterpenoid derivatives and specialty odorants.
• Flavor Enhancement: Used in trace amounts to create or enhance unique flavor profiles in specialty food and beverage applications.
• Cosmetic Ingredients: Incorporated into high-end cosmetic products for its fragrance properties and potential as a precursor for active ingredients.
• Research & Development: Utilized in academic and industrial R&D for studying structure-odor relationships and developing new synthetic methodologies.
• Household & Industrial Fragrances: Applied in the formulation of long-lasting air fresheners, detergents, and fabric softeners.
