Description

3-Methyl-5-[(2,2,3-Trimethyl-3-Cyclopenten-1-Yl)Methyl]-2-Cyclohexen-1-Ol CAS NO 71820-54-7 is a high-value fragrance intermediate and synthetic building block known for its complex woody and amber-like olfactory characteristics. This compound is prized for its ability to impart long-lasting, sophisticated notes in fine fragrance compositions. It is primarily utilized by manufacturers in the flavor and fragrance (F&F) industry, as well as by research chemists developing novel aroma chemicals and specialty fine chemicals.

Application

• Fine Fragrance Formulation: A key ingredient in premium perfumes, colognes, and eau de toilettes to create woody, ambery, and musky base notes.
• Functional Fragrance Products: Used in personal care items (soaps, shampoos, lotions) and household products (detergents, fabric softeners) for scent stability and diffusion.
• Aroma Chemical Synthesis: Serves as a crucial intermediate for the synthesis of more complex fragrance molecules and specialty terpenoids.
• Flavor Enhancement: Employed in trace amounts to add depth and complexity to certain flavor profiles, subject to regulatory approval.
• Research & Development: Used in academic and industrial R&D for studying structure-odor relationships and developing new synthetic pathways.

Quality Control

Our 3-Methyl-5-[(2,2,3-Trimethyl-3-Cyclopenten-1-Yl)Methyl]-2-Cyclohexen-1-Ol is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC and GC-MS, to ensure high purity, consistent olfactory profile, and batch-to-batch reliability essential for fragrance applications. Certificates of Analysis (COA) detailing purity, identity, and specific impurity profiles are available upon request.

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 nature, keep containers tightly sealed when not in use to prevent evaporation and potential changes in concentration. Keep away from heat, sparks, and open flame.
