Synthesis
Saccharic acid can be prepared by oxidizing both the aldehydic and primary alcohol groups in an aldose, such as glucose, forming the dicarboxylic acid.[5][6] A suitable reagent for this transformation is boiling 30% nitric acid, resulting in a yield of 50% to 65%.[6] This reaction was first described by German chemist Heinrich Kiliani in 1925.[7]
Uses
Detergents
The sodium salt has found use in dishwasher detergents, where it acts as a chelating agent for calcium and magnesium ions.[7] It is considered more environmentally friendly than phosphates, which are more commonly encountered in detergent formulations.[7][8]
Dietary supplement

Saccharic acid salts have found use in dietary supplements, where they act as precursors to the β-glucuronidase inhibitor saccharolactone (d-glucaro-1,4-lactone).[4] Some preclinical studies have demonstrated saccharolactone to have anticancerogenic and detoxification properties, although more clinical research is needed to confirm health impacts in humans.[9][10][11]
