Quality Control

Our deuterated standards are produced under strict quality protocols to ensure the highest isotopic purity and chemical integrity. Each batch is characterized by NMR and mass spectrometry to confirm the degree of deuteration and chemical purity. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically >98 atom % D), chemical purity (by GC or HPLC), and other relevant parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) in a dry environment. For long-term stability, storage at 2-8°C is recommended.
