L-Glutathione oxidized disodium salt is the disodium salt of glutathione disulfide (GSSG), the oxidized dimer of glutathione, widely used as an oxidizing agent and disulfide source (for example in GSH/GSSG redox buffers that promote disulfide bond formation during protein refolding) and research reagent in biochemical studies, pharmaceutical formulations, and food science applications. This disodium salt variant enhances solubility and stability for experimental and industrial use. CAS 103239-24-3, molecular formula C20H30N6Na2O12S2, molecular weight 656.59 g/mol. Store at -15 to -20°C for long-term stability. Non-hazardous under normal handling conditions.
