Description

Phosphoric Acid-17O4 is a stable isotope-labeled derivative of phosphoric acid, where four oxygen atoms are enriched with the non-radioactive isotope Oxygen-17. This compound is essential for advanced research and analytical applications requiring precise isotopic tracing. It is primarily utilized by scientists and manufacturers in the fields of nuclear magnetic resonance (NMR) spectroscopy, metabolic pathway studies, and the development of labeled pharmaceutical compounds.

Application

• NMR Spectroscopy: Used as an internal standard or chemical shift reference in 17O NMR studies.
• Metabolic Research: Acts as a tracer for studying phosphate metabolism and energy transfer pathways in biological systems.
• Pharmaceutical Development: Employed in the synthesis of isotopically labeled drug candidates for pharmacokinetic and metabolic stability studies.
• Geochemical Tracing: Applied in environmental science to trace phosphate sources and cycling in ecosystems.
• Catalysis Research: Serves as a probe molecule for investigating reaction mechanisms on catalyst surfaces.
• Material Science: Used in the development of specialty glasses and ceramics where isotopic purity can influence material properties.

Quality Control

Every batch of Phosphoric Acid-17O4 is produced and tested under stringent conditions to ensure exceptional isotopic and chemical purity. We provide comprehensive Certificates of Analysis (COA) detailing isotopic enrichment (Atom % 17O), chemical purity, and absence of critical impurities. Our quality systems are designed to meet the exacting requirements of research and pharmaceutical development.

Storage

Preserve in a tightly closed container, protected from light. Store at room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its nature as a strong acid, ensure containers are made of compatible materials (e.g., PTFE, HDPE) and are kept separate from bases and reactive materials.
