Application

Butyric anhydride is a clear liquid primarily used in the manufacture of butyrates, which are important in various industrial applications. It plays a crucial role in the production of drugs and tanning agents due to its chemical properties. Despite its strong odor, similar to that of butyric acid, this compound also serves as a fumigant in beekeeping products like Bee-Go, where it effectively drives bees from their hives.
