Description

Nitrogen-15N is a stable, non-radioactive isotope of nitrogen, distinguished by its enriched 15N nucleus. This isotopic label is a critical tool in advanced research and analytical chemistry, enabling precise tracking and quantification of nitrogen atoms in complex systems. It is essential for scientists and industries requiring high-fidelity isotopic tracers for metabolic studies, environmental analysis, and the development of labeled compounds.

Application

• Metabolic Pathway Tracing: Used as a stable isotopic tracer in biomedical and agricultural research to study nitrogen assimilation, protein turnover, and plant nutrient uptake.
• Environmental Science: Employed in studies of nitrogen cycling in ecosystems, groundwater contamination (e.g., nitrate sources), and atmospheric chemistry.
• Nuclear Magnetic Resonance (NMR) Spectroscopy: Serves as an active NMR nucleus (15N NMR) for elucidating molecular structure, dynamics, and interactions in organic chemistry, biochemistry, and material science.
• Pharmaceutical Research & Development: Used to synthesize isotopically labeled drug candidates and metabolites for pharmacokinetic, metabolic stability, and mass spectrometry (MS) quantification studies.
• Analytical Chemistry Standards: Acts as an internal standard for isotope dilution mass spectrometry (IDMS), ensuring high accuracy in quantitative analysis.
• Chemical Synthesis: A key starting material for producing a wide range of 15N-labeled fine chemicals, intermediates, and reagents.
