Cyclodecanone is primarily used in organic synthesis as a building block for the production of more complex chemical compounds. It serves as a key intermediate in the manufacture of fragrances and flavors, contributing to the creation of unique scent profiles in perfumes and aromatic products. Additionally, it is utilized in the development of polymers and resins, where it enhances properties such as flexibility and durability. In pharmaceutical research, cyclodecanone is employed in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, aiding in the discovery of new therapeutic agents. Its application in material science includes the production of specialty chemicals and coatings, where it improves performance characteristics.
