Description

Costol CAS NO 515-20-8 is a naturally occurring sesquiterpene alcohol, valued for its role as a key intermediate and building block in organic synthesis and fragrance chemistry. Its unique bicyclic structure makes it a versatile starting material for the production of more complex molecules. This compound is of significant interest to research and development laboratories, as well as manufacturers in the flavors & fragrances, pharmaceutical intermediates, and fine chemical sectors.

Application

• Fragrance and Flavor Intermediate: Serves as a precursor in the synthesis of novel aroma chemicals and flavoring agents, contributing woody, amber, or earthy notes.
• Pharmaceutical Research: Used as a chiral building block or starting material in the research and development of active pharmaceutical ingredients (APIs) and bioactive compounds.
• Organic Synthesis: Acts as a versatile intermediate for the preparation of complex natural products, specialty chemicals, and other sesquiterpenoid derivatives.
• Cosmetic Ingredients: Employed in the development of high-value cosmetic actives and specialty ingredients where natural-origin molecules are preferred.
• Chemical Reference Standard: Supplied as a high-purity standard for analytical testing, quality control, and method development in laboratories.
