Description

Urea-15N2 is a stable isotope-labeled analog of urea, where both nitrogen atoms are the non-radioactive isotope Nitrogen-15. This product is essential for advanced research and analytical applications requiring precise isotopic tracing. It is primarily used by scientists and manufacturers in the pharmaceutical, agricultural, and environmental sectors for metabolic studies, quantitative proteomics, and as an internal standard in mass spectrometry.

Application

• Metabolic Pathway Research: Used as a tracer to study nitrogen metabolism and urea cycle dynamics in biological systems.
• Quantitative Proteomics & Mass Spectrometry: Serves as a critical internal standard for accurate protein quantification and metabolic flux analysis.
• Agricultural & Environmental Science: Employed in studies of fertilizer uptake, nitrogen fixation, and soil nutrient cycling.
• Pharmaceutical Development: Utilized in drug metabolism and pharmacokinetics (DMPK) studies to track the fate of nitrogen-containing compounds.
• Clinical Diagnostics: Acts as a reference standard in advanced assays for measuring urea and related metabolites.
• NMR Spectroscopy: Provides a valuable tool for structural elucidation and reaction monitoring in synthetic chemistry.
