Quality Control

Our Pyrogallol is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We offer grades suitable for industrial, technical, and reagent applications. Quality is verified through comprehensive analytical testing, including assay, identification, and impurity profiling. A Certificate of Analysis (COA) detailing specific test results is provided with each shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its nature as an easily oxidized (store under inert atmosphere) and light-sensitive (store away from light) compound, prolonged exposure to air or light should be avoided to maintain product integrity. Keep away from strong oxidizing agents.
