Mannitol hexanitrate is a powerful explosive. Physically, it is a powdery solid at normal temperature ranges, with density of 1.73 g/cm3. The chemical name is hexanitromannitol and it is also known as nitromannite, MHN, and nitromannitol, and by the trademarks Nitranitol and Mannitrin. It is more stable than nitroglycerin, and it is used in detonators. Mannitol hexanitrate is a secondary explosive formed by the nitration of mannitol, a sugar alcohol Wikipedia
