Description

2-[2-(2,2,3-Trimethyl-3-Cyclopenten-1-Yl)Ethylidene]-1-Pentyl Acetate is a high-value fragrance intermediate and aroma chemical prized for its unique woody, amber, and leathery olfactory characteristics. This compound is essential for creating sophisticated, long-lasting scent profiles in premium product formulations. It is primarily utilized by manufacturers in the fragrance and flavor, cosmetic, and personal care industries seeking to enhance the complexity and performance of their end products.

Application

• Fragrance & Flavor Industry: A key building block for creating complex perfume accords, particularly in woody, amber, fougère, and chypre fragrance families for fine perfumery, colognes, and air care products.
• Cosmetic & Personal Care: Used as a fragrance ingredient in a wide range of products including lotions, soaps, shampoos, deodorants, and other toiletries to impart a rich, persistent scent.
• Household & Industrial Products: Incorporated into detergents, fabric softeners, cleaning agents, and other household products to provide a pleasant and stable fragrance note.
• Functional Perfumery: Employed in functional applications where scent-masking or long-lasting fragrance is required, such as in industrial coatings, polymers, or specialty chemicals.
• Aroma Chemical Synthesis: Serves as a valuable intermediate for the synthesis of other, more complex fragrance molecules and specialty aroma chemicals.

Quality Control

Our fragrance ingredients are produced and tested under strict quality management systems to ensure consistent olfactory profile, purity, and stability. Quality is verified against rigorous internal specifications and industry benchmarks. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each batch to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at controlled room temperature (15-25°C/59-77°F). Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) after opening and minimize headspace in partially used containers to maintain product integrity.
