Beryllium nitrate, also called beryllium dinitrate, is the ionic beryllium salt of the nitric acid HNO3. Its molecular formula is Be(NO3)2, and its molecular weight is 133.021982.
Like all beryllium-containing chemical compounds, beryllium nitrate is toxic. It irritates the throat when inhaled in small doses, while the inhalation of a larger amount may cause acute pneumonitis. It causes the skin and eyes to become red from irritation. The substance itself is not combustible; however, it produces toxic fumes when it comes in contact with a flame. It is also toxic to the environment, especially to aquatic organisms, and care should be taken to ensure its safe storage in a well-closed container.
