Description

Cyclopentadec-4-En-1-One is a high-purity macrocyclic ketone, a key building block in the synthesis of complex fragrance molecules. Its unique 15-membered ring structure with an internal double bond provides a valuable template for creating musky, animalic, and amber-like olfactory notes. This compound is essential for research and development chemists in the fine fragrance, flavor, and specialty chemical industries seeking to develop novel aroma profiles or study macrocyclic chemistry.

Application

• Fragrance & Flavor Intermediate: A crucial precursor in the synthesis of high-value macrocyclic musks (e.g., muscone analogs) and other specialty aroma chemicals.
• Fine Chemical Synthesis: Serves as a versatile building block for pharmaceutical research, agrochemicals, and advanced material science due to its complex cyclic structure.
• Academic & Industrial Research: Used in organic chemistry research for studying ring-closing metathesis, hydrogenation reactions, and the properties of medium-ring compounds.
• Specialty Polymer Modifiers: Potential application as a monomer or modifier to impart specific olfactory or structural characteristics to polymers.
