Used primarily as a nitrogen-15 labeled compound in research and scientific studies. It serves as a tracer in environmental and agricultural research to study nitrogen cycling, soil fertility, and plant nutrient uptake. In analytical chemistry, it aids in the development of precise methods for nitrogen detection and quantification. Additionally, it is utilized in isotopic labeling experiments to understand chemical and biological processes involving nitrogen. Its stable isotope properties make it valuable in nuclear magnetic resonance (NMR) spectroscopy for structural analysis.
