Quality Control

Our 502U83 is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with every shipment, detailing all relevant specifications. Our quality commitment aligns with cGMP principles where applicable, supporting its use in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants.
