Chemistry, Properties & Perfumer Guide
The Chemistry
Amyl cinnamate is an ester formed from cinnamic acid and amyl alcohol. It belongs to the class of aromatic esters commonly used in perfumery for their sweet, balsamic properties. Industrially, it’s synthesized via Fischer esterification, where cinnamic acid reacts with pentanol under acidic conditions. The resulting compound has good stability and blends well with both floral and oriental accords.
