Used as a key intermediate in the synthesis of antioxidants and polymer stabilizers due to its strong reducing properties. Employed in research for its ability to chelate metal ions, enhancing stability in formulations. Serves as a reagent in analytical chemistry for detecting oxidative enzymes. Also investigated for potential biological activity in pharmaceutical studies, particularly in pathways involving redox regulation. Its trihydroxy structure makes it useful in developing dyes and photographic developers where controlled electron donation is required.
