Dinitrogen monoxide is its IUPAC name and its common name is laughing gas. Its chemical name is nitrous oxide itself.
Dinitrotoluene is frequently used as a plasticizer, deterrent coating, and burn rate modifier in propellants (e.g., smokeless gunpowders). As it is carcinogenic and toxic, modern formulations tend to avoid its use. In this application it is often used together with dibutyl phthalate.
