Quality Control

Our Isorhamnetin glycoside is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the stringent requirements for research and standard-grade materials. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) or under refrigeration (2-8°C) for long-term stability. Due to its sensitivity, the product should be stored under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Keep the container in a dry, cool, and well-ventilated area.
