Quality Control

Our Physodic Acid is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity confirmation and spectroscopic methods for identity verification, to ensure it meets high-purity research-grade standards. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting batch-specific results for transparency and traceability.

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 light-sensitive nature and propensity to be easily oxidized, it is recommended to store the material under an inert atmosphere for long-term stability. Keep the container tightly sealed in a dry environment to prevent any potential moisture uptake.
