用途四:该品具有强烈而持久的茉莉香气及浓而温和的果香，常用作化妆品香精的香原料。
方法一:有多种合成法，将茉莉酮催化还原，或将2,5-十一烷二酮在氢氧化钠乙醇溶液中缩合，或由丙烯酸酯与重辛醇在过氧化物催化下缩合，然后脱水重排，都可制得二氢茉莉酮。十一烷二酮法。将2,5-十一烷二酮、乙醇、2%氢氧化钠溶液在氮气保护下加热回流6h，将反应液浓缩后用石油醚提取，提取液蒸除溶剂后减压蒸馏，收集113-115℃（1.33kPa）馏分，即得成品。
用途二:通常微量用于香精配方。在果香-花香型中可以提调花香之气势，如用于茉莉、依兰、铃兰、玉兰、晚香玉等花香型香精中。微量与果香共用，可产生愉快的头香。它有增强香柠檬、薰衣草、杂薰草、香紫苏和其他药草香型的香气功能。在柑橘型香精中可得好的底香。
