Description

Sodium Azide-15N3 CAS NO 1015486-10-8 is a stable isotope-labeled analog of sodium azide, where all three nitrogen atoms are the heavier nitrogen-15 (15N) isotope. This compound is critical for advanced research and analytical applications where isotopic tracing is required, providing a non-radioactive, safe method for tracking molecular pathways. It is an essential reagent for pharmaceutical development, metabolic studies, and proteomics research in academic, biotechnology, and contract research organizations.

Application

• Isotopic Labeling in Pharmaceutical Research: Used as a precursor for synthesizing 15N-labeled compounds for pharmacokinetic and metabolic stability studies.
• Mass Spectrometry & Proteomics: Serves as a reagent in quantitative proteomics workflows, such as in chemical labeling techniques for protein and peptide analysis.
• NMR Spectroscopy: Employed to synthesize 15N-enriched molecules for nuclear magnetic resonance (NMR) studies, enhancing signal resolution and structural elucidation.
• Chemical Biology & Biochemistry: Utilized in click chemistry and bioorthogonal reactions to introduce azide groups into biomolecules for conjugation and imaging.
• Environmental & Geochemical Tracer Studies: Applied as a stable isotopic tracer in environmental science to study nitrogen cycling and transformation processes.
• Reference Standard Manufacturing: Acts as a high-purity starting material for producing certified reference standards (CRMs) for analytical laboratories.
