Description

4(15),11-Oppositadien-1-Ol is a specialized sesquiterpene alcohol with a unique bicyclic structure. This compound serves as a valuable intermediate and building block in the synthesis of complex natural products and fine chemicals. It is particularly relevant for research and development laboratories, flavor and fragrance houses, and pharmaceutical companies seeking novel chiral synthons.

Application

• Flavor and Fragrance (F&F) Industry: Used as a key intermediate or starting material for the synthesis of novel aroma chemicals and perfumery ingredients with woody, earthy, or amber nuances.
• Pharmaceutical Research: Acts as a chiral building block in the synthesis of potential drug candidates and for studying structure-activity relationships (SAR) in medicinal chemistry.
• Natural Product Synthesis: Serves as a precursor in the total or semi-synthesis of complex sesquiterpenoids and other natural compounds for academic and industrial research.
• Agrochemical Intermediates: Utilized in the development of new active ingredients or pheromones due to its specific bicyclic framework.
• Fine Chemical Production: Employed in custom synthesis and contract manufacturing for producing high-value, specialized chemicals.
