Description

Ethyl Alcohol-17O CAS NO 255043-66-4 is a stable isotope-labeled analog of ethanol, where the standard oxygen-16 atom is replaced with the non-radioactive oxygen-17 isotope. This compound is essential for advanced research and analytical applications requiring precise molecular tracing and quantification. It is primarily utilized by scientists and manufacturers in the pharmaceutical, metabolic research, and analytical chemistry sectors for use as an internal standard, tracer, or reagent in mass spectrometry, NMR spectroscopy, and kinetic studies.

Application

• Internal standard for the quantitative analysis of ethanol and related compounds in biological matrices using Gas Chromatography-Mass Spectrometry (GC-MS) or Liquid Chromatography-Mass Spectrometry (LC-MS).
• Tracer compound in metabolic pathway studies and pharmacokinetic research to investigate the fate of ethanol in biological systems.
• Reagent for the synthesis of other oxygen-17 labeled compounds for specialized research applications.
• Use in Nuclear Magnetic Resonance (NMR) spectroscopy as a probe for studying molecular structure, dynamics, and interactions.
• Calibration standard for high-precision isotopic ratio measurements in environmental and forensic analysis.
• Component in the development and validation of diagnostic assays and clinical testing methods.

Quality Control

Our Ethyl Alcohol-17O is produced and handled under strict quality protocols to ensure isotopic and chemical purity for sensitive research applications. Each batch is characterized by advanced analytical techniques including NMR and Mass Spectrometry to confirm isotopic enrichment and chemical identity. A comprehensive Certificate of Analysis (COA) detailing isotopic purity (atom % 17O), chemical purity, and solvent content is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at controlled room temperature (15-25°C). Due to its highly volatile nature, keep away from heat, sparks, and open flame. For long-term stability, consider storage under an inert atmosphere.
