1-(2,6,6-Trimethyl-2-cyclohexen-1-yl)-2-buten-1-one

Alpha-Damascone (1-(2,6,6-Trimethyl-2-cyclohexen-1-yl)-2-buten-1-one) is a powerful macrocyclic-type ketone fragrance molecule belonging to the damascone family, renowned for its intensely rosy, fruity, and slightly woody-tobacco character with exceptional tenacity even at very low concentrations. It occurs naturally in trace amounts in rose absolute and certain other floral extracts, but is predominantly produced synthetically for commercial use due to its scarcity in nature. Formulators prize alpha-Damascone for its remarkable diffusivity and longevity, as well as its ability to add depth and naturalness to floral, oriental, and chypre fragrance compositions at usage levels typically below 0.1%.
