Description

Diethyleneglycol Monoethyl-D5 Ether is a deuterated analog of a key glycol ether solvent, where five hydrogen atoms are replaced with deuterium, offering unique isotopic properties for advanced research and analytical applications. This compound is valued for its role as a stable, non-exchangeable deuterium label and as a solvent in specialized spectroscopic studies. It is primarily needed by researchers and manufacturers in the pharmaceutical, agrochemical, and analytical chemistry sectors for use in NMR spectroscopy, mass spectrometry, and as a tracer in metabolic and kinetic studies.

Application

• As a deuterated solvent for Nuclear Magnetic Resonance (NMR) spectroscopy, providing a non-interfering signal in proton NMR analysis.
• As an internal standard or tracer in mass spectrometry and pharmacokinetic studies due to its isotopic stability.
• In the synthesis of deuterated fine chemicals and active pharmaceutical ingredients (APIs) for research and development.
• As a specialty solvent in electrolyte formulations for advanced battery research.
• For use in organic synthesis where deuterium labeling is required to study reaction mechanisms.
• In the formulation of deuterated lubricants and functional fluids for specialized industrial applications.

Quality Control

Our deuterated chemicals are produced and tested under strict quality management systems. Each batch of Diethyleneglycol Monoethyl-D5 Ether is analyzed to ensure high isotopic purity and chemical purity suitable for sensitive analytical applications. Certificates of Analysis (COA) detailing isotopic enrichment (e.g., D atom %), chemical assay, and impurity profiles are provided and available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers should be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from strong alkalis and incompatible materials.
