(4E)-4-Heptenal, with the CAS number 929-22-6, is an unsaturated aldehyde characterized by its seven-carbon chain and a double bond located at the fourth carbon from the aldehyde functional group. This compound is known for its distinctive odor, often described as fatty or green, which makes it of interest in the flavor and fragrance industries. It is a colorless to pale yellow liquid at room temperature and is soluble in organic solvents but has limited solubility in water due to its hydrophobic nature. The presence of the aldehyde functional group contributes to its reactivity, allowing it to participate in various chemical reactions, including oxidation and condensation. (4E)-4-Heptenal can be synthesized through several methods, including the aldol condensation of appropriate precursors. Its applications extend beyond flavoring agents to potential uses in organic synthesis and as a building block in the production of more complex molecules. Safety considerations include handling it in well-ventilated areas and using appropriate personal protective equipment, as it may cause irritation upon contact with skin or eyes.
