  • Applications

    rel-(2E)-1-[(1R,2S)-2,6,6-Trimethyl-3-cyclohexen-1-yl]-2-buten-1-one (CAS number: ) is an aroma-chemical used primarily in perfumery as an odorant with violet- and green-note characteristics; it is also encountered as a fragrance component in cosmetics and personal care products, and may be evaluated for use as a flavor/aroma ingredient in limited food-related applications; it can be employed in household products such as cleaners and air fresheners to impart distinctive notes; and it serves as an intermediate or building block in industrial manufacturing for the synthesis of other ionone-type fragrance compounds, including derivatives used in coatings, inks, and plastics.
