5-DOXYL-stearic Acid, Free Radical (>90%) (Cat No.:C000648) is a chemical compound containing a stable free radical, often used as a spin label in electron paramagnetic resonance (EPR) spectroscopy. The “DOXYL” moiety refers to the nitroxide radical that serves as a spin label, allowing researchers to probe the local environment and dynamics of biomolecules like lipids and proteins. Incorporating this label into stearic acid provides a tool for studying molecular interactions, conformational changes, and membrane dynamics.
