A green, fresh floral aromachemical with a distinct hyacinth-narcissus character and an earthy, slightly rooty undertone. The acetal form is milder and more stable than free phenylacetaldehyde, giving a cleaner leafy-floral effect without the harsh, aldehydic bite. Persists longer than the parent aldehyde, adding natural-smelling green-floral lift to bouquets.AI · claude-opus-4-7
