Product Information

Osmium tetroxide solution, a 4 wt. % concentration in water, is a powerful oxidizing agent widely utilized in various fields, including organic chemistry and histology. This compound is particularly valued for its ability to selectively stain lipids and unsaturated fatty acids, making it an essential tool in microscopy and biological research. Researchers often employ osmium tetroxide in the preparation of biological specimens, enhancing contrast in electron microscopy, which allows for detailed visualization of cellular structures.

In addition to its applications in microscopy, osmium tetroxide is also used in organic synthesis, particularly in the oxidation of alkenes to form vicinal diols through a process known as osmylation. This reaction is crucial for the synthesis of complex organic molecules, providing chemists with a reliable method for functionalizing hydrocarbons. The unique properties of osmium tetroxide, such as its high reactivity and ability to form stable complexes, make it a valuable asset in both academic and industrial laboratories, facilitating advancements in chemical research and development.
