(E)-5-Methyl-2-hepten-4-one is an organic compound characterized by its structure as a ketone with a double bond, specifically located between the second and third carbon atoms of a heptane chain. This compound features a methyl group at the fifth carbon position, contributing to its unsaturation and influencing its reactivity and physical properties. It is typically a colorless to pale yellow liquid with a distinctive odor, which may be reminiscent of certain fruit or floral notes, making it of interest in flavor and fragrance applications. The presence of the double bond and the ketone functional group imparts specific chemical reactivity, including susceptibility to nucleophilic addition reactions. Its boiling point and solubility characteristics suggest it is moderately volatile and may dissolve in organic solvents. Additionally, (E)-5-Methyl-2-hepten-4-one may exhibit biological activity, which could be relevant in various fields such as pharmaceuticals or agrochemicals. Safety data should be consulted for handling and exposure guidelines, as with any chemical substance.
