  • Applications

    (Z)-7-Hexadecenal is used as a fragrance ingredient in perfumery, contributing green, waxy aldehydic notes to both new and established formulations. It may also be employed as a minor aroma component in flavor formulations. In cosmetics and personal care, it can function as a fragrance additive in products such as creams, lotions, and soaps. In household products and cleaners, it may be used as a fragrance constituent in air fresheners and cleaning agents. In industrial manufacturing, it often serves as an intermediate in organic synthesis, supporting the production of other fragrance materials or pheromone-related compounds. In agriculture, it can be used as a component in pheromone blends for pest management, for monitoring or mating disruption, depending on formulation and regulatory requirements.
