Quality Control

Every batch of 5-Pahsa-D31 is manufactured under strict quality management systems and undergoes comprehensive analytical characterization. We guarantee high chemical and isotopic purity, verified by NMR, HPLC, and mass spectrometry. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming identity, purity, and deuterium enrichment. Our quality commitment ensures reliability for your most sensitive research applications.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to ensure long-term stability, as the material is hygroscopic (moisture-sensitive). Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture ingress.
