Quality Control

Our deuterated compounds are produced under strict quality protocols to ensure high isotopic purity and chemical integrity. Each batch of 4-Methoxyphenol-2,3,5,6-D4 is characterized by NMR and mass spectrometry to confirm deuterium incorporation and chemical purity. Certificates of Analysis (COA) detailing isotopic enrichment, assay, and impurity profiles are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 15-25°C. This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). For long-term storage, consider packaging under an inert gas such as argon or nitrogen.
