4-Oxo-TEMPO (CAS 2896-70-0)

4-Oxo-TEMPO (CAS 2896-70-0) is a highly stable, water-soluble nitroxide radical. Widely used as a spin probe in electron paramagnetic resonance (EPR) studies, it also acts as a powerful catalyst in organic synthesis, an antioxidant to stabilize polymers, and a contrast agent for metabolic imaging
Formula: C₉H₁₆NO₂
Appearance: Orange to light brown crystalline powder

Major Applications
Biomedical & Research: Utilized in metabolic tracking and hypoxic sensitivity studies within MRI and EPR spectroscopy. It mimics superoxide dismutase (SOD) to reduce harmful superoxide radicals in cells.
Industrial Synthesis: Employed as an oxidation catalyst in the pharmaceutical industry to synthesize drug molecules.
Polymer Chemistry: Functions as an effective polymerization inhibitor for acrylates, styrenics, and methacrylates during high-temperature processing and storage
