Quality Control

Our Przewalskinic Acid A is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with customer specifications and relevant research-grade standards.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. The compound is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere when appropriate. Allow the sealed container to equilibrate to room temperature before opening to prevent condensation.
