Used in the fragrance industry for its floral, waxy, and slightly citrus-like aroma, particularly in perfumes and scented cosmetics. It serves as a key intermediate in the synthesis of pheromones for pest control in agriculture, helping to disrupt mating behaviors of certain insect species. Also employed in flavor formulations to impart fresh, green, and aldehydic notes in food products. Its long-chain unsaturated aldehyde structure makes it valuable in organic synthesis for creating complex aroma chemicals.
