Quality Control

Our Tris(2-Ethylhexyl) Phosphate-D51 is produced under strict quality management systems to ensure isotopic purity and chemical integrity. Each batch is characterized by advanced spectroscopic methods, including NMR and Mass Spectrometry, to confirm deuteration level and chemical identity. Certificates of Analysis (COA) detailing isotopic enrichment (typically >98 atom % D), chemical purity, and analytical results are provided to support your research and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Keep away from strong acids and incompatible materials such as strong oxidizing agents. For long-term stability, consider storage under an inert atmosphere.
