4Decanone

4-Decanone, also known as decan-4-one or nonan-4-one, is an aliphatic ketone with the formula C10H18O. In the decan-4-one arrangement, the carbonyl group is located at the fourth carbon of a ten-carbon chain. The molecule is linear, with the structural formula CH3-CH2-CH2-CO-CH2-CH2-CH2-CH2-CH2-CH3.

Physically, 4-decanone is a colorless liquid at room temperature. It is relatively hydrophobic and is immiscible with water, but soluble in many organic solvents such as ether and acetone. Its boiling point is comparatively high for a ketone of its size due to the long hydrocarbon chain.

In terms of applications, 4-decanone is used as a solvent and as an intermediate in organic synthesis. It may also be present as a minor component in refined petroleum fractions. Like other ketones, it can serve as a building block for the preparation of other chemicals through standard carbonyl chemistry.

Safety and handling considerations are typical for medium-chain ketones: 4-decanone is flammable and should be kept away from heat, sparks, and open flames. It can cause skin and eye irritation. Adequate ventilation, anti-exposure measures, and appropriate personal protective equipment should be used when handling the compound, and storage should be in a cool, well-ventilated area away from oxidizing agents.
