nitrogen tetroxide
Nitrogen tetroxide (N2O4) is a chemical compound made up of nitrogen and oxygen. At room temperature, it appears as a reddish-brown gas and can easily convert to a colorless liquid under pressure. It is often used as an oxidizer in rocket propellants due to its ability to facilitate combustion. Nitrogen tetroxide is significant in both industrial applications and environmental science, where it plays a role in the formation of nitrogen oxides, contributing to air pollution. Its properties require careful handling, as it can be toxic and corrosive.
