Überblick
Shipped in solution with sulfuric acid (solutions are usually 40% nitrosylsulfuric acid and 54% sulfuric acid (Hawley)). Solution is a straw-colored oily liquid with a sharp odor. When pure, a crystalline solid decomposing at 73 °C. Very irritating to skin and eyes. Used to make dyes and other chemicals.
