Description

Ethylene-D4 Glycol is a deuterated analog of ethylene glycol, where the hydrogen atoms are replaced with deuterium, a stable isotope of hydrogen. This isotopic labeling makes it an essential tool in advanced research and analytical chemistry, particularly for use as an internal standard in mass spectrometry and NMR spectroscopy. It is critical for scientists and industries requiring precise molecular tracking, structural elucidation, and metabolic studies in pharmaceutical development, material science, and chemical synthesis.

Application

• Internal standard for quantitative analysis via Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS).
• Deuterated solvent and tracer in Nuclear Magnetic Resonance (NMR) spectroscopy for molecular structure determination.
• Precursor in the synthesis of deuterated polymers and advanced materials for research.
• Key reagent in pharmaceutical research for drug metabolism and pharmacokinetics (DMPK) studies.
• Used in the development and calibration of analytical instruments and methods.
• Essential for metabolic pathway tracing and proteomics research in life sciences.
• Employed in organic synthesis where deuterium labeling is required to study reaction mechanisms.

Quality Control

Our Ethylene-D4 Glycol is produced under stringent conditions to ensure high isotopic purity and chemical integrity. Each batch undergoes rigorous quality testing, including analysis by NMR, GC-MS, and IR spectroscopy, to confirm deuterium enrichment and the absence of protiated impurities. A comprehensive Certificate of Analysis (COA) detailing isotopic purity, chemical purity, and assay is provided with every shipment to ensure compliance with your research and analytical standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed tightly after use to prevent absorption of atmospheric moisture, which can affect isotopic purity.
