Description

Nitro-15N-Benzene CAS NO 3681-79-6 is a stable isotope-labeled derivative of nitrobenzene, where the nitrogen atom is enriched with the Nitrogen-15 (15N) isotope. This labeling is critical for applications requiring precise molecular tracking and analysis, as it provides a non-radioactive, detectable marker. It is an essential building block and tracer compound for researchers and manufacturers in pharmaceutical development, agrochemical research, and advanced material science, where understanding reaction pathways and metabolic fate is paramount.

Application

• Pharmaceutical Research & Development: Used as an internal standard and tracer in mass spectrometry (MS) and nuclear magnetic resonance (NMR) studies for drug metabolism and pharmacokinetics (DMPK).
• Agrochemical Science: Serves as a labeled precursor in the synthesis and environmental fate studies of pesticides and herbicides.
• Analytical Chemistry: Employed as a calibration standard and reference material in quantitative NMR (qNMR) and isotope dilution mass spectrometry for accurate quantification.
• Organic Synthesis: Acts as a key labeled intermediate for the synthesis of more complex 15N-labeled aromatic compounds, dyes, and polymers.
• Environmental Tracing: Utilized in studies to track the breakdown and transformation of nitroaromatic compounds in ecological systems.
• Metabolomics & Proteomics: Facilitates the labeling of biomolecules for advanced research in metabolic flux analysis and protein dynamics.
