Quality Control

Our Purpurogallin is manufactured under a quality management system to ensure batch-to-batch consistency. Each lot undergoes comprehensive analytical testing, including identification by FT-IR, purity assay by HPLC, and control of related substances. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with the agreed 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 sensitivity to light and tendency for oxidation, it is recommended to store the product under an inert atmosphere for long-term stability and to minimize exposure to air upon opening.
