Rosefuran (3-methyl-2-prenylfuran) is a liquid boiling at 103-104°C (at 50mm Hg), with a density of 0.9089 g/cm3 (at 30°C), less than that of water. It is an aroma chemical which is a minor constituent of the aroma of the rose (Rosa damascene). Rosefuran is a 2,3-disubstituted furan (3-methyl-2-(3-methyl-2-buten-1-yl)furan). It has an odor threshold of 200 ppb and constitutes 0.16% of Bulgarian rose oil. Rosefuran has been established as a female sex pheromone of an acarid mite, Caloglyphus sp. Concentrations of less than 100ng of synthetic rosefuran caused sexual excitation in males of the species.
