Quality Control

Our Cletoquine-D4 Oxalate is manufactured under strict quality systems to ensure the highest isotopic purity and chemical stability required for analytical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment, chemical purity, and identity confirmation via advanced spectroscopic techniques. We adhere to relevant guidelines for the production of reference standards.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) or as indicated on the label or COA. This material is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability.
