Quality Control

Every batch of 3'',4''-Di-o-p-Coumaroylquercitrin is manufactured and controlled under a strict quality management system. We provide comprehensive analytical documentation to support your regulatory and research needs. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) with detailed HPLC purity data are available upon request.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a low-humidity environment. For long-term storage, consider desiccants or inert atmosphere to maintain stability.
