Uric Acid-1,3-15N2 is primarily used in research and diagnostic applications due to its isotopic labeling. It serves as a valuable tool in metabolic studies, particularly in tracing nitrogen metabolism pathways in biological systems. Researchers utilize it to investigate purine metabolism and disorders such as gout or hyperuricemia, where uric acid levels are elevated. Its labeled nitrogen atoms enable precise tracking and analysis in mass spectrometry or nuclear magnetic resonance (NMR) studies. Additionally, it aids in the development of diagnostic assays for detecting uric acid-related conditions, contributing to improved understanding and management of metabolic diseases.
