Description

Nitrogen-15N Dioxide, 99 Atom % 15N is a stable isotope-labeled form of nitrogen dioxide, distinguished by its high isotopic enrichment of 99 atom % 15N. This high isotopic purity is critical for applications requiring precise tracking and quantification of nitrogen species, eliminating background interference from natural abundance isotopes. It is an essential reagent for researchers and industrial scientists in the fields of atmospheric chemistry, tracer studies, and advanced material synthesis. The compound is supplied under strict quality control to ensure reliability for sensitive analytical and synthetic procedures.

Application

• Isotopic Tracer Studies: Used as a labeled precursor in environmental and biological research to track nitrogen oxide (NOx) reaction pathways, transformation, and fate in complex systems.
• Atmospheric Chemistry Research: Enables detailed mechanistic studies of photochemical smog formation, ozone depletion cycles, and other gas-phase reactions under controlled, isotopically labeled conditions.
• Analytical Method Development: Serves as an internal standard or calibration standard in advanced spectroscopic techniques like Isotope Ratio Mass Spectrometry (IRMS) for accurate NOx quantification.
• Materials Science: Employed in the chemical vapor deposition (CVD) or surface nitridation processes to introduce 15N labels into semiconductors, catalysts, or thin films for subsequent analysis.
• Chemical Synthesis: Acts as a specialized oxidizing agent or nitrating agent in the synthesis of 15N-labeled organic compounds, pharmaceuticals, or coordination complexes.

Quality Control

Every batch of Nitrogen-15N Dioxide is produced and analyzed to meet exacting standards for isotopic and chemical purity. Our quality assurance protocol includes verification by Isotope Ratio Mass Spectrometry (IRMS) and FT-IR spectroscopy to confirm isotopic enrichment and chemical identity. A comprehensive Certificate of Analysis (COA) detailing the isotopic atom percent, chemical purity, and gas composition is provided with each shipment to ensure traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed, specially designed cylinder or container, protected from light and stored in a cool, well-ventilated area. Due to its nature as a highly volatile and strong oxidizer, it must be kept away from heat, sparks, open flames, and incompatible materials such as organic compounds and reducing agents. Store at room temperature (15-25°C) and ensure the container is upright and securely fastened.
