Quality Control

Our Orientin is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and related substance analysis. A Certificate of Analysis (COA) detailing identity, purity, and residual solvent profiles is provided with every shipment to support your quality assurance protocols.

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 nature, the container must be kept tightly sealed in a low-humidity environment to prevent moisture absorption and degradation.
