Butyl nitrate is a colorless oil. It is often confused with butyl nitrite, which is sometimes used as a recreational inhalant.^[1]

Safety

Butyl nitrate is an explosive.^{[ citation needed ]} It reacts explosively with Lewis acids such as boron trifluoride and aluminium chloride. When heated to decomposition, it emits fumes of nitrous oxide.^[2]
