In dilution it opens fresh and juicy but quickly reveals a rich, greasy fried-fat facet reminiscent of chicken skin or beef tallow.AI · claude-opus-4-7

This aldehyde provides new notes in the almost trivial 'aldehydic' topnote theme. It introduces very fine notes in Citrus oils, particularly Grapefruit and Bitter Orange, and it blends well with the conventional aliphatic aldehydes in woody, mossy or citrusy compositions. As a trace ingredient in top-note compositions for floral fragrances, it has also good possibilities.
Produced by double addition of Acetaldehyde to Octanal, or by condensation of Crotonaldehyde with Octanal.
