有醚样气味。能与水、醇类、醚类、酮类、酯类和烃类混溶。易燃。有刺激性。 

四氢呋喃(THF)是一种饱和环醚，主要用作有机溶剂。长期储存时，它会形成有机过氧化物。可通过添加丁基羟基甲苯(BHT)作为稳定剂而抑制这一过程。BHT能去除形成过氧化物所需的自由基。它是各种天然产物（聚醚类抗生素）的关键片段。THF可与硫化氢形成双水合物，其晶体结构已经过三维单晶研究法进行过研究。
应用：
干燥四氢呋喃(THF)已用于合成二氯{双[1,1′，1′′-(膦三基)三哌啶]钯[(P(NC5H10)3)2Pd(Cl)2]，广泛用作Heck反应中的催化剂。它已被用于各种芳基溴和烯烃的Heck交叉偶联反应介质。

A heterocyclic polar solvent and polymer precursor.

Tetrahydrofuran (THF) is a saturated cyclic ether that is mainly used as an organic solvent. When stored for a long time, it forms organic peroxides. This process can be inhibited by adding butylhydroxytoluene (BHT) as a stabilizer. BHT removes free radicals needed to form peroxides. It is a key fragment of various natural products (polyether antibiotics). THF can form double hydrates with hydrogen sulfide, and its crystal structure has been studied by three-dimensional single crystal method.
Application：
Dried tetrahydrofuran (THF) has been used to synthesize dichloride {bis [1,1 ',1 "-(phosphine triyl) tripiperidine] palladium [(P(NC5H10)3)2Pd(Cl)2], which is widely used as a catalyst in Heck reactions. It has been used as a Heck cross-coupling reaction medium for various aryl bromine and olefin.
