Description and Uses
Nitromethane (75-52-5) is an explosive material that was originally manufactured for various applications including mining, construction, demolition, law enforcement, and military uses. However, due to threats of terrorism and increased attention to accident prevention, regulations concerning the transportation, storage, use, and transfer relating to explosives have steadily increased over the last few years and manufacturing limited.
Solvent; chemical synthesis; fuel for professional and model racing cars; in explosive mixtures
