CAS 7697-37-2: Nitric acid

Description: Nitric acid, with the CAS number 7697-37-2, is a highly corrosive and strong mineral acid characterized by its colorless to yellowish appearance and pungent odor. It is a powerful oxidizing agent and is soluble in water, forming a highly exothermic reaction upon dilution. Nitric acid has a molecular formula of HNO₃ and typically exists in concentrated form as a solution containing about 68% nitric acid by weight. It is known for its ability to react with a wide range of metals, often producing nitrogen oxides and other nitrogen-containing compounds. Due to its strong acidity, it can cause severe burns upon contact with skin or tissue. Nitric acid is widely used in various industrial applications, including the production of fertilizers, explosives, and in the manufacturing of plastics and dyes. Additionally, it plays a crucial role in the synthesis of nitro compounds and serves as a reagent in laboratories for various chemical reactions. Proper handling and storage are essential due to its hazardous nature.
