Used in the fragrance industry for its fresh, floral, and slightly citrus-like aroma, (2E)-hexadecenal is a key component in perfumery, particularly in floral scents such as lily and magnolia. It enhances the top to middle notes in fine fragrances and is valued for its ability to impart a natural, green floral character. Due to its low odor threshold, it is effective at low concentrations, making it efficient in complex scent formulations. It is also explored in flavor applications for its potential to contribute to fruity and waxy notes, though its use in food is limited and carefully regulated.
