Function:
- TEMPO is a stable nitroxide free radical that acts as a catalyst in oxidation reactions.
- As an antioxidant, TEMPO can remove reactive oxygen species from the reaction system and protect compounds from oxidative damage. In some scientific studies, TEMPO is used to study the effects of oxidative stress on organisms.
Application:
- A common catalyst for oxidizing alcohols to aldehydes or ketones, it is widely used in drug synthesis, fine chemicals and other fields.
- It can be used for the epoxidation of olefins to generate epoxy compounds.
- TEMPO and its derivatives can react with biological molecules (such as proteins, nucleic acids, etc.) to achieve the labeling and detection of biological molecules.
- Because TEMPO has antioxidant function, it has potential application value in the treatment of some diseases.
