Quality Control

Our deuterated compounds are produced and handled under strict quality control protocols to ensure isotopic purity and chemical integrity. Each batch is characterized by advanced spectroscopic and chromatographic techniques, including NMR and HPLC-MS. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically >98 atom % D), chemical purity, and analytical data is provided with every shipment to support your research and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. Allow the sealed container to reach room temperature before opening to prevent condensation and moisture ingress. Store in a cool, dry, and well-ventilated area.
