2-Methyltetrahydrofuran is an organic compound with the molecular formula CH3C4H7O. It is a highly flammable mobile liquid. It is mainly used as a replacement for THF in specialized applications for its better performance, such as to obtain higher reaction temperatures, or easier separations (as, unlike THF, it is not miscible with water). It is derived from furfural and is usable as a biofuel.

生产方法
由2-甲基呋喃催化加氢而得。当催化加氢反应采用氯化钯催化剂时,主要的产品是乙酰丙醇(见00420),但也可回收得到副产品2-甲基四氢呋喃。 用于医药磷酸氯喹中间体。
用途
用于医药磷酸氯喹中间体。
