Quality Control

Our Theogallin is produced under a strict quality management system to ensure batch-to-batch consistency and high purity suitable for research and commercial use. Each lot undergoes comprehensive analytical testing, including HPLC for purity verification and identity confirmation by spectroscopic methods. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee compliance with your requirements.

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 oxidation, it is recommended to store the product under an inert atmosphere for long-term preservation. Keep the container tightly sealed to minimize exposure to air and moisture.
