Quality Control

Every batch of 2,4,6-Tri-o-Galloylglucose is manufactured under a strict quality management system and undergoes comprehensive analytical testing to ensure it meets the highest standards for research and development. Our quality commitment includes identity confirmation by spectroscopic methods and purity assessment by chromatographic techniques. A detailed Certificate of Analysis (COA) providing batch-specific data for identity, purity, and related substances is provided with each shipment to support your regulatory and quality assurance 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, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal stability. Keep the container tightly sealed in a dry environment to minimize exposure to atmospheric moisture.
