Quality Control

Our 2,4,6-Trihydroxybenzoic Acid Potassium Salt is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing specific results for assay, impurities, and physical parameters is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere to minimize the risk of oxidation.
