Quality Control

Our Potassium p-Methoxyphenolate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, moisture content, and impurity profiles. We can support production under cGMP guidelines for pharmaceutical applications upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
