Quality Control

Our Baicalin is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, heavy metals screening, and residual solvent analysis, to ensure it meets high-grade standards suitable for pharmaceutical and nutraceutical applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles 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 sealed in a low-humidity environment to prevent degradation.
