Description

Acetic-18O 2 Acid CAS NO 17217-83-3 is a stable isotope-labeled analog of acetic acid, where the oxygen-18 (18O) isotope is incorporated into the carbonyl group. This compound is an essential tool in research and analytical chemistry, serving as a non-radioactive tracer for mechanistic studies, metabolic pathway analysis, and quantitative mass spectrometry. It is primarily used by scientists and quality control professionals in the pharmaceutical, agrochemical, and academic research sectors who require precise tracking of molecular pathways and high-accuracy analytical standards.

Application

• As an internal standard for the accurate quantification of acetic acid and related metabolites in complex biological matrices via Gas Chromatography-Mass Spectrometry (GC-MS) or Liquid Chromatography-Mass Spectrometry (LC-MS).
• As a tracer in metabolic flux analysis to study the Krebs cycle, fatty acid synthesis, and other biochemical pathways in living systems.
• For mechanistic organic chemistry studies, investigating reaction pathways, isotopic exchange, and kinetic isotope effects.
• In the synthesis of other 18O-labeled compounds, including pharmaceuticals, agrochemicals, and advanced materials.
• For calibration and method development in environmental testing and food safety analysis to ensure regulatory compliance.
• In nuclear magnetic resonance (NMR) spectroscopy as a probe for molecular structure and dynamics.

Quality Control

Our Acetic-18O 2 Acid is produced and tested to meet the exacting standards required for research and analytical applications. Each batch is rigorously analyzed to ensure high chemical and isotopic purity. Certificates of Analysis (COA) are provided, detailing parameters such as isotopic enrichment (Atom % 18O), chemical purity by GC or HPLC, and identity confirmation by IR or NMR. We adhere to strict quality management protocols to ensure batch-to-batch consistency and reliability for your critical experiments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at room temperature (15-25°C). Due to its highly volatile nature, ensure containers are securely sealed when not in use and stored away from heat sources and open flames.
