cyclononanone

Cyclononanone is a cyclic ketone with the chemical formula C9H16O. It is a nine-membered ring structure containing a carbonyl group. It is a colorless liquid at room temperature with a characteristic odor. Cyclononanone is soluble in many organic solvents but has limited solubility in water. It is a relatively stable compound under normal conditions.

This compound can be synthesized through various methods, including the oxidation of cyclononanol or the cyclization of appropriate dicarboxylic acid derivatives. It finds applications in organic synthesis as a building block for more complex molecules. Its ring size and functional group make it a useful intermediate in the production of pharmaceuticals, fragrances, and other specialty chemicals. Research into its properties and reactivity continues to explore its potential in various chemical processes. Due to its cyclic nature, it can exhibit different stereoisomers depending on the position of substituents, though cyclononanone itself is achiral. The conformational flexibility of the nine-membered ring also influences its chemical behavior.
