Dihydroxyfumaric acid hydrate（Cat No.:M131549）is a hydrated dicarboxylic acid derivative structurally related to fumaric acid and oxalic acid. It is a highly reactive intermediate studied in biochemical and metabolic research, particularly in pathways involving oxidative stress and redox balance. Due to its instability and tendency to undergo oxidation, it is often used in controlled experimental systems to investigate radical-mediated reactions, organic acid metabolism, and mitochondrial function. The hydrate form enhances handling for laboratory applications, supporting studies in metabolic regulation, enzymology, and disease mechanisms linked to reactive oxygen species.
