Quality Control

Our Praziquantel-D11 is manufactured under strict quality systems to ensure the highest isotopic and chemical purity required for sensitive analytical applications. Each batch undergoes comprehensive testing, including NMR and Mass Spectrometry for isotopic enrichment verification and HPLC for chemical purity assessment. A detailed Certificate of Analysis (COA) providing batch-specific data on purity, isotopic enrichment, and solvent content is supplied with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as indicated on the label or COA. Due to its hygroscopic nature, the material should be handled in a controlled, low-humidity environment and sealed under inert gas after opening for long-term stability.
