Pentaerythritol tetranitrate is an organic nitrate that has been used for the treatment of angina pectoris. Upon administration, the drug undergoes exstensive metabolism to NO which causes vasodilation and the relaxation of smooth muscle cells. The compound belongs to a familiy of explosive substances and may be used accordingly.

Manganese Dinitrate Hexahydrate is a highly water soluble crystalline salt composed of manganese and nitrate with formula Mn(NO3)2. In nature, manganese nitrate is found in the form of hydrates, most common is the tetrahydrate Mn(NO3)2•4H2O, but mono- and hexahydrates are also known as well as the anhydrous compound. On heating to 300°C, aqueous solutions of manganese(II) nitrate thermally decompose to form MnO2 and NO2 as products. Manganese(II) nitrate can be prepared by dissolving manganese(II) carbonate in dilute nitric acid, it can also be prepared from manganese dioxide and nitrogen dioxide Manganese Dinitrate is an important intermediate in the production of high-purity manganese oxides and is also used in the preparation of colorants for the ceramics industry.
