WebDimethyl Sulfoxide (DMSO) Compatibility Compatible with 10% DMSO. This structural characteristic makes DMSO a potent scavenger of free radicals, particularly hydroxyl (OH), which is the most reactive free radical in biological systems. It is believed that DMSO protects the integrity of cell membranes during injury,48 especially defending against attack by hydroxyl radicals, which are generated at a high level after ischemic injury.
