Used in pharmaceutical research and development, particularly in studies related to gout and hyperuricemia. High-purity uric acid serves as a reference standard in analytical testing to calibrate instruments and validate methods for uric acid quantification in biological samples. It is also employed in enzyme activity assays, especially for uricase enzymes, to assess metabolic pathways and drug efficacy. In dermatology, purified uric acid is investigated for its antioxidant properties and role in skin health. Additionally, it is utilized in the formulation of diagnostic reagents and in quality control processes within clinical laboratories.
