Quality Control

Our Raparin is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including HPLC for purity assay and identity confirmation. Certificates of Analysis (COA) documenting all critical quality attributes are available for each batch upon request, supporting compliance in regulated applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
