Description:Trans-2-heptenal is an unsaturated aldehyde characterized by its linear chain structure and the presence of a double bond between the second and third carbon atoms, along with an aldehyde functional group at one end. Its molecular formula is C7H12O, and it features a trans configuration, which influences its physical properties and reactivity. This compound is typically a colorless to pale yellow liquid with a distinctive, pleasant odor reminiscent of green apples or fresh grass, making it of interest in the flavor and fragrance industries. Trans-2-heptenal is soluble in organic solvents but has limited solubility in water due to its hydrophobic nature. It is known for its reactivity, particularly in undergoing oxidation and addition reactions, which can lead to the formation of various derivatives. Additionally, it is used as an intermediate in organic synthesis and can be found in certain natural products. Safety considerations include its potential irritant effects, necessitating proper handling and storage protocols.
