Description

(+)-Copalol CAS NO 10395-43-4 is a high-purity, naturally derived sesquiterpene alcohol known for its distinct woody and ambergris-like olfactory profile. This compound is valued for its role as a key fragrance intermediate and building block in the synthesis of complex aroma chemicals. It is primarily sought after by manufacturers in the fragrance and flavor industry, as well as by research institutions focused on organic synthesis and natural product chemistry.

Application

• Fragrance & Flavor Industry: Serves as a crucial intermediate and starting material for the synthesis of high-value aroma chemicals with woody, amber, and animalic notes.
• Perfumery: Used as a building block to create novel synthetic ambergris substitutes and other complex fragrance compounds for fine fragrances and personal care products.
• Organic Synthesis: Acts as a chiral synthon in academic and industrial research for the preparation of more complex terpenoids and natural product analogs.
• Aroma Chemical Production: Employed in the manufacturing of specialty odorants for functional perfumery in detergents, cosmetics, and household products.
• Research & Development: Utilized as a standard or reference material in analytical chemistry and sensory science studies.
