  • Applications

    2,6,10-Trimethyl-9-undecenal (CAS 141-13-9) is primarily used as an aroma ingredient and odorant in perfumery, contributing to and helping stabilize the fragrance profile in perfume formulations. It is also used in cosmetics and personal care as a fragrance component. In household products such as cleaners and air fresheners, it can serve as an odorant or fragrance additive. In industrial manufacturing, it is often employed as an intermediate in the synthesis of other fragrance compounds or as a scent-release building block in coatings and inks. It may be considered for flavor applications in foods at low levels, subject to regulatory limits.
