Application

4-Carboxy-2,2,6,6-tetramethylpiperidine 1-Oxyl Free Radical serves as a versatile compound with several key applications. It functions as a potent catalyst for the oxidation of regenerated cellulose, such as viscose rayon, into cellouronic acid. This compound is a derivative of TEMPO, characterized by a carboxy group at the fourth position, making it a significant member of the aminoxyl class. Its immobilization with 3-aminopropylsilane on mesoporous silica creates a robust heterogeneous catalytic system, suitable for a variety of oxidation reactions. Additionally, 4-Carboxy-TEMPO plays roles beyond catalysis, acting as a radical scavenger, an MRI contrast agent, and a spin label, highlighting its multifunctional nature and broad utility in different scientific and industrial applications.
