Used primarily in organic synthesis, especially in the preparation of fragrances and flavoring agents due to its aromatic character and structural features. It serves as an intermediate in the production of pharmaceuticals and fine chemicals, where its cinnamic acid backbone allows for further functionalization. Its methoxy-substituted aromatic ring enhances stability and influences reactivity, making it valuable in the development of light-sensitive compounds and photostabilizers. Also explored in the synthesis of certain UV-absorbing materials for use in cosmetics and coatings.
