一般描述

4-甲基-2-戊酮已经在柠檬香精[1]、意大利栗子[2]和蟹肉的挥发性成分中得到鉴定。[3]

应用


  • 依普利酮在 13 种纯溶剂中从 283.15 到 323.15 K 的热力学分析：本研究详细分析了依普利酮的溶解度行为和热力学，为其在溶剂选择和药物配方中的应用提供了宝贵的见解（Liu 等人，2024 年）。

  • 开发和验证用于蜂蜜挥发性目标化合物和可疑化合物测定的高通量顶空固相微萃取气相色谱-质谱方法：本文提出了一种分析蜂蜜中挥发性化合物的方法，其中使用 4-甲基-2-戊酮来增强对香气化合物的检测，这对于质量控制和真实性评估至关重要（Gialouris 等人，2023 年）。
