Description

2-(6,10,10-Trimethylbicyclo[7.2.0]Undeca-2,5-Dien-2-Yl)Ethyl Acetate is a high-purity synthetic intermediate and fragrance ingredient characterized by its unique bicyclic terpenoid structure. This compound matters for its role in creating complex, long-lasting woody and ambergris-type olfactory profiles in fine perfumery and functional fragrance applications. It is primarily needed by manufacturers in the fragrance and flavor industry, as well as by research chemists developing novel organic molecules for specialty chemical synthesis.

Application

• Fine Fragrance Formulation: Serves as a key building block for sophisticated woody, amber, and musk accords in premium perfumes, colognes, and eau de toilettes.
• Functional & Consumer Product Fragrancing: Used in air care products, detergents, fabric softeners, and personal care items (soaps, shampoos) to impart stable and appealing scent characteristics.
• Flavor & Food Industry: May be employed in trace amounts to create complex flavor nuances, subject to appropriate regulatory approvals and purity grades (e.g., FCC).
• Organic Synthesis Intermediate: Acts as a versatile starting material or intermediate in the synthesis of more complex terpenoid derivatives and specialty chemicals for pharmaceutical or agrochemical research.
• Aromatherapy & Wellness Products: Incorporated into essential oil blends and diffuser products for its potential aromatic properties.

Quality Control

Our 2-(6,10,10-Trimethylbicyclo[7.2.0]Undeca-2,5-Dien-2-Yl)Ethyl Acetate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, GC-MS, and NMR, to ensure identity, purity, and olfactory profile consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We can supply material compliant with IFRA guidelines and relevant FCC or COSMOS standards upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C/59-77°F). This material is easily oxidized (store under inert atmosphere) and is compatible with strong acid/organic solvent. Keep away from heat, sparks, and open flame. For long-term storage, consider packaging under an inert gas such as nitrogen or argon.
