Sodium nitrite-¹⁵N is a form of sodium nitrite where the nitrogen atom is replaced by the stable isotope nitrogen-15. This isotopic labeling is used to study nitrogen metabolism and the behavior of nitrites in various chemical processes. Sodium nitrite-¹⁵N is valuable in tracer studies, helping to elucidate reaction mechanisms, identify nitrogen transfer pathways, and investigate the environmental fate of nitrites. Its applications span environmental chemistry, analytical chemistry, and pharmaceuticals, particularly in understanding nitrite interactions and transformations in biological and chemical systems.
