Quality Control

Our 3,4-Di-o-Galloylquinic Acid is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, MS), to ensure it meets the high standards required for research and industrial use. Certificates of Analysis (COA) detailing purity, related substances, and residual solvents are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is easily oxidized (store under inert atmosphere) and is light-sensitive (store away from light). For long-term storage, consider inert gas purging and refrigeration (2-8°C).
