Description

Octahydro-7,7,8,8-Tetramethyl-2,3B-Methano-3Bh-Cyclopenta[1,3]Cyclopropa[1,2]Benzene-4-Methyl Formate is a high-purity synthetic fragrance intermediate known for its unique woody and amber-like olfactory profile. This compound is valued for its stability and potency, making it a critical building block for creating sophisticated, long-lasting scent accords. It is primarily sought by manufacturers in the flavor and fragrance (F&F) industry, as well as producers of high-end personal care and household products requiring consistent, high-quality aroma chemicals.

Application

• Fine Fragrance Formulation: As a key ingredient in premium perfumes, colognes, and eau de toilettes to impart woody, ambery, and musky base notes.
• Personal Care Products: Used in scented lotions, soaps, shampoos, and deodorants to provide a stable and persistent fragrance character.
• Household & Institutional Cleaners: Incorporated into air fresheners, fabric softeners, and detergents for long-lasting scent delivery.
• Functional Perfumery: Employed in technical applications where scent masking or functional aromas are required.
• Flavor Enhancers: Potential use in trace amounts to create complex flavor profiles, subject to appropriate regulatory compliance (e.g., FCC, FEMA GRAS).
• Aroma Chemical Synthesis: Serves as a versatile intermediate for the synthesis of other specialty fragrance molecules.
