Phenethyl tiglate (CAS 55719-85-2) — Floral Top to middle Note Fragrance Ingredient
Phenethyl tiglate
CAS 55719-85-2
What Is Phenethyl tiglate?
Phenethyl tiglate is a synthetic fragrance ingredient used in perfumes and personal care products. It adds a fruity, floral character reminiscent of roses with a hint of tropical fruit. You’ll encounter it in floral bouquets and fruity fragrances. This molecule matters because it bridges floral and fruity accords, offering perfumers a versatile tool for creating modern, complex scents. Its stability makes it valuable in formulations where longevity is desired.
Safety Profile
GENERALLY SAFEWhat Does Phenethyl tiglate Smell Like?
Phenethyl tiglate unfolds with an initial burst of ripe pear and tropical fruit, quickly revealing a lush rose heart with hints of honeyed sweetness. As it evolves, the scent develops a velvety texture reminiscent of peach skin, settling into a soft floral-woody drydown. The fruity top notes persist longer than expected, creating an unusual bridge between fresh and voluptuous accords. Imagine biting into a perfectly ripe Bartlett pear while smelling a bouquet of dew-covered tea roses.
In Famous Fragrances

Chemistry, Properties & Perfumer Guide
The Chemistry
Phenethyl tiglate is an ester formed by the reaction of phenethyl alcohol with tiglic acid. This unsaturated ester belongs to the class of phenylpropanoids, though it’s produced synthetically. The trans-configuration of the tiglate moiety contributes to its distinctive fruity character. Industrial synthesis typically involves acid-catalyzed esterification under controlled conditions to prevent isomerization.
