3β-DOXYL-5α-cholestane, free radical is a spin label for EPR studies and electron spin-lattice relaxation times in aqueous dispersions. 3β-DOXYL-5α-cholestane, a free radical, is a crucial element in several scientific research applications. It is extensively employed in the study of transversal relaxation of nitroxides for PELDOR in phospholipid membranes, allowing researchers to gain insights into the effects of cholesterol on bicelle model membranes through comparative studies. Moreover, it serves as a spin probe for investigating electron spin-lattice relaxation times in aqueous dispersions using saturation recovery techniques. Additionally, it plays a vital role in probing cooperative and local modes of poly(Me acrylate) samples using ESR and in studying the impact of hydrophobic aerosil′s random disorder on the order and dynamics of the probe in 5CB nematic liquid crystals.
