A fatty, waxy aldehyde with a green-citrus lift reminiscent of melon rind and cucumber skin. The unsaturated tail gives it a slightly oily, ozonic-fresh nuance beneath the sharp aldehydic top. Bridges classic C9/C10 fatty aldehyde character with a more natural, dewy green facet.AI · claude-opus-4-7
