Used in perfumery and flavoring due to its aromatic properties, 3-Hydroxyperillaldehyde contributes fresh, herbal, and slightly citrusy notes to fragrances and functional products. It serves as an intermediate in the synthesis of fine chemicals and natural product derivatives, particularly in the development of terpenoid-based compounds. Its structural features make it valuable in organic synthesis for creating bioactive molecules with potential applications in pharmaceuticals and agrochemicals. Additionally, it may be explored in aromatherapy and cosmetic formulations for its sensory profile.
