1nonanone

1-Nonanone, also known as nonan-1-one or enanthone, is a ketone with the chemical formula C9H18O. It is a colorless liquid at room temperature with a characteristic odor. Its structure consists of a nine-carbon chain with a carbonyl group located at the first carbon atom. This means it is an aldehyde, not a ketone. However, the common name enanthone is sometimes used.

1-Nonanone is found in some essential oils and is used in the flavor and fragrance industry. It can contribute fruity or floral notes to perfumes and food products. While it occurs naturally, it can also be synthesized industrially for commercial use.

The chemical properties of 1-nonanone are typical of aldehydes. It can undergo oxidation to form nonanoic acid. It also participates in various organic reactions, such as nucleophilic addition at the carbonyl carbon. Its relatively low molecular weight and volatility make it useful in certain applications where controlled evaporation is desired. Safety precautions should be taken when handling 1-nonanone, as with any organic chemical, to avoid skin or eye contact and ensure adequate ventilation.
