Quality Control

Our Purpurogallincarboxylic Acid is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and residual solvent analysis. A detailed Certificate of Analysis (COA) is provided with every shipment, ensuring traceability and compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its nature as an easily oxidized compound, prolonged storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal long-term stability. Keep away from strong oxidizing agents.
