A protected acetal form of phenylacetaldehyde with a citronellyl-methyl twist — softer and more stable than free phenylacetaldehyde, giving a green-floral hyacinth character with rosy and slightly citronella-leafy nuances. Less sharp and honeyed than the parent aldehyde, with a cleaner, more diffusive floral-green quality.AI · claude-opus-4-7
