Quality Control

Every batch of our Okadaic Acid Potassium Salt is produced and tested under strict quality management protocols to ensure the highest standards of purity and consistency for research use. Our quality control includes rigorous analytical testing via HPLC, NMR, and MS to confirm identity, potency, and purity. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment, ensuring full traceability and compliance with research-grade specifications.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake. For long-term storage, consider under an inert atmosphere.
