Description

Nitric Acid (15N) is a stable isotope-labeled form of nitric acid, where the nitrogen atom is the non-radioactive isotope Nitrogen-15. This product is essential for advanced research and analytical applications requiring precise isotopic tracing. It is particularly valuable for scientists and industries involved in metabolic studies, environmental analysis, and the development of labeled compounds. The high chemical purity and isotopic enrichment ensure reliable and reproducible results in sensitive experimental protocols.

Application

• Isotopic Tracer Studies: Used in agricultural and environmental research to track nitrogen pathways in soil, plants, and ecosystems.
• Metabolic Research: A key reagent in biomedical and pharmacological studies for investigating nitrogen metabolism and protein synthesis.
• NMR Spectroscopy: Serves as a starting material or standard for the synthesis of 15N-labeled compounds used in Nuclear Magnetic Resonance (NMR) analysis.
• Mass Spectrometry Standards: Employed as an internal standard or calibration reference in quantitative mass spectrometry to improve accuracy.
• Chemical Synthesis: Used in the production of other 15N-enriched fine chemicals, pharmaceuticals, and research compounds.
• Geochemical Analysis: Applied in studies of nitrogen cycles in oceans, atmosphere, and geological formations.

Quality Control

Our Nitric Acid (15N) is produced and handled under stringent quality management systems to ensure batch-to-batch consistency and reliability for critical research. Each lot is characterized for key parameters including isotopic enrichment (15N atom %), chemical purity, and absence of critical metallic impurities. A comprehensive Certificate of Analysis (COA) detailing assay, isotopic purity, and specific tests is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area, away from incompatible materials such as organic compounds, strong reducing agents, and bases. Due to its nature as a strong acid and oxidizer, containers must be kept upright and secure to prevent leakage or rupture. Recommended long-term storage temperature is between 15°C and 25°C.
