Quality Control

Our Wilforlide B 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 determination. A Certificate of Analysis (COA) detailing purity, identity, and other critical parameters is provided with every shipment to guarantee compliance with your research and manufacturing specifications.

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 product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to minimize exposure to atmospheric humidity. For long-term storage, consider using desiccants.
