Description

Potassium Nitrite (15N) is a stable isotope-labeled inorganic salt, where the nitrogen atom is enriched with the 15N isotope. This compound is critical for advanced research and analytical applications requiring precise isotopic tracing and quantification. It is primarily utilized by scientists and manufacturers in the fields of nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry, agricultural research, and pharmaceutical development.

Application

• Isotopic Tracer Studies: Used as a 15N-labeled precursor in metabolic pathway research and environmental fate studies.
• Analytical Chemistry Standards: Serves as a certified reference material (CRM) for quantitative NMR (qNMR) and isotope-ratio mass spectrometry (IRMS) calibration.
• Pharmaceutical Research: Employed in the synthesis of isotopically labeled drug molecules and metabolites for pharmacokinetic and bioavailability studies.
• Agricultural Science: Applied in nitrogen cycle research to track fertilizer uptake, utilization efficiency, and soil nitrogen transformations.
• Geochemical Analysis: Used in paleoclimatology and oceanography studies as a stable isotope standard.
• Material Science: Acts as a doping agent or precursor in the synthesis of specialized materials where 15N incorporation is required.
