Description

2-Methyl-4-(2,2,3-Trimethyl-3-Cyclopenten-1-Yl)-2-Butenyl Acetate is a high-value fragrance intermediate and aroma chemical prized for its unique woody, amber, and slightly fruity olfactory profile. This compound matters for formulators seeking to create sophisticated, long-lasting, and complex scent accords in premium consumer products. It is primarily needed by manufacturers in the fragrance and flavor, personal care, and household goods industries for applications requiring a rich, diffusive, and stable woody character.

Application

• Fine Fragrance: A key ingredient in perfumes, eau de toilettes, and colognes, contributing to woody, amber, and chypre base notes.
• Personal Care Products: Used in scented lotions, soaps, shampoos, and deodorants to impart a luxurious and persistent fragrance.
• Household & Air Care: Incorporated into fabric softeners, detergents, candles, and air fresheners for a warm and inviting ambient scent.
• Flavor Enhancer: Employed in trace amounts to add subtle fruity or woody nuances to certain food and beverage flavorings.
• Functional Fragrances: Used in industrial deodorants or masking agents for technical products.
• Aroma Chemical Synthesis: Serves as a valuable building block for the synthesis of other complex fragrance molecules.

Quality Control

Our fragrance-grade 2-Methyl-4-(2,2,3-Trimethyl-3-Cyclopenten-1-Yl)-2-Butenyl Acetate is produced under strict quality management systems to ensure consistent olfactory profile, purity, and stability. Each batch is analyzed against stringent internal specifications for identity, assay, and key impurities. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from heat, sparks, and open flame. Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain optimal quality and shelf life.
