  • Applications

    2-Methyltetradecanal is primarily used as a fragrance ingredient and odorant in perfumery, providing a long-chain aldehydic note typical of this class. It is commonly evaluated for use in cosmetics and personal care products as a scent component, and may serve as a fragrance fixative to help extend fragrance longevity. In household products, it can contribute to scent profiles in air fresheners and cleaners. It may be employed in industrial manufacturing as an intermediate or additive in fragrance formulations, and in coatings or inks to modify or impart aroma characteristics. Use is subject to regulatory limits and formulation guidelines.
