CAS 29817-79-6
:nitrogen-15N
Description:
Nitrogen-15 (15N) is a stable isotope of nitrogen, which is a non-metal element with the atomic number 7. It is characterized by having seven protons and eight neutrons in its nucleus, giving it a mass number of 15. This isotope is naturally occurring, albeit in small amounts, constituting about 0.36% of all nitrogen found in nature. Nitrogen-15 is primarily used in various scientific applications, including tracer studies in biological and environmental research, as it can be incorporated into organic molecules without altering their chemical properties. Its unique nuclear properties also make it valuable in nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry. The CAS number 29817-79-6 specifically identifies this isotope, distinguishing it from other nitrogen isotopes, such as nitrogen-14, which is more abundant. Overall, nitrogen-15 plays a crucial role in advancing our understanding of nitrogen cycling in ecosystems and in the study of metabolic processes in living organisms.
