Used primarily as a solvent in the production of cellulose-based materials, particularly in the Lyocell process for manufacturing fibers. It effectively dissolves cellulose without causing significant degradation, enabling the creation of environmentally friendly textiles. Additionally, it serves as an oxidizing agent in organic synthesis, facilitating the conversion of alcohols to carbonyl compounds. Its role in polymer chemistry is also notable, aiding in the modification and stabilization of polymers. In research, it is utilized for its ability to dissolve and study complex biomolecules.
