2,2,6,6-四甲基-3,5-庚二酮（TMHD）不溶于水（0.02g/100mL），是一种高效萃取溶剂。铕和镨与TMHD形成的螯合物可用做NMR位移试剂，在GC分析试验中可分析Al,Be,Cr和稀土金属。同时，TMHD作为配体备受青睐。它与多种金属形成的金属配合物，可以用作MOCVD前驱体和均相反应的催化剂，并能有效提高苛刻条件反应（如Ullmann反应）收率。

美国STREM工厂提供各种高纯度、品质卓越的2,2,6,6-四甲基-3,5-庚二酮金属化合物，满足不同研究领域需求。

2008 年百灵威与STREM 正式签署战略合作协议，全权负责STREM 在中国市场的产品销售、技术应用与支持等各项业务。百灵威始终秉承“资源共享，共同发展”之理念，一如既往地为中国化学行业广大科研和生产用户提供品质卓越的有机金属、配体、催化剂等产品及服务！
