7-Octen-1-ol is an unsaturated alcohol with a fresh, green, leafy odor, commonly used directly in the fragrance and flavor industries to impart a sense of freshness in products such as perfumes, soaps, lotions, and body care items. Due to its alcohol functionality and reactive double bond, it serves as a versatile intermediate in organic synthesis, particularly for creating longer-chain unsaturated alcohols, cyclic derivatives, or other compounds in perfumery. Its structure enables functionalization through hydrogenation, oxidation, or cyclization, making it valuable in fine chemical manufacturing. Additionally, it is explored as a building block for biologically active molecules and specialty polymers.
