Used primarily as a nitrogen-15 labeled compound in agricultural research to study nitrogen uptake and metabolism in plants. It serves as a tracer in soil science to monitor nitrogen movement and efficiency in fertilizers. In biochemistry, it aids in NMR spectroscopy for analyzing protein structures and metabolic pathways. Additionally, it is employed in environmental studies to track nitrogen pollution and its impact on ecosystems. Its isotopic labeling makes it valuable for precise and controlled experiments in various scientific fields.
