Description

2-[2-(2,2,3-Trimethyl-3-Cyclopenten-1-Yl)Ethylidene]Cyclopentanol is a high-value fragrance intermediate and synthetic musk precursor known for its unique woody, amber, and musky olfactory characteristics. This compound matters for formulators seeking to create sophisticated, long-lasting, and complex scent profiles in premium consumer products. It is primarily needed by manufacturers in the fragrance and flavor industry, as well as by R&D laboratories developing novel aroma chemicals.

Application

• Fragrance Formulation: A key building block for creating woody, amber, and musk accords in fine perfumery for perfumes, colognes, and personal care products.
• Functional Perfumery: Used in household and industrial products such as detergents, fabric softeners, and air fresheners to provide a stable, substantive base note.
• Flavor Enhancement: Employed in trace amounts to add complexity and depth to certain flavor profiles where woody or earthy notes are desired.
• Synthetic Musk Production: Serves as a critical precursor in the synthesis of macrocyclic and polycyclic musk compounds.
• Chemical Intermediate: Utilized in organic synthesis for the production of other specialty chemicals with modified cyclopentanol structures.
• Research & Development: A valuable compound for academic and industrial research into new odorants and the structure-activity relationships of fragrance molecules.

Quality Control

Our 2-[2-(2,2,3-Trimethyl-3-Cyclopenten-1-Yl)Ethylidene]Cyclopentanol is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including GC, IR, and NMR, to ensure identity, purity, and olfactory consistency. Certificates of Analysis (COA) detailing purity, specific gravity, refractive index, and organoleptic properties are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C/59-77°F). Due to its highly volatile nature, keep containers tightly sealed when not in use and away from heat sources and open flames.
