Uric acid sodium salt is commonly used in biochemical research as a standard or reference compound for the quantification and analysis of uric acid levels in various biological samples. It plays a significant role in studies related to gout, kidney function, and metabolic disorders, where uric acid concentration is a critical parameter. Additionally, it is utilized in the preparation of culture media for certain microorganisms that require uric acid as a nitrogen source. In clinical diagnostics, it serves as a calibrator in assays to measure uric acid in blood or urine, aiding in the diagnosis and monitoring of conditions like hyperuricemia or hypouricemia. Its application extends to the development of biosensors and enzymatic assays for detecting uric acid in medical and environmental samples.
