Abstract

4,8-Dimethyl-3,7-nonadien-2-ol in which the weight ratio of (E)-4,8-dimethyl-3,7-nonadien-2-ol to the sum of (E)- and (Z)-4,8-dimethyl-3,7-nonadien-2-ol is at least 80% or in which the weight ratio of (Z)-4,8-dimethyl-3,7-nonadien-2-ol to the sum of (E)- and (Z)-4,8-dimethyl-3,7-nonadien-2-ol is at least 80%, is used as fragrance. The fragrances have a unique rose-like, floral character. Citrus-like, minty, green accompanying notes reminiscent of rhubarb arise.
