Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is analyzed to confirm identity, purity, and consistency. Certificates of Analysis (COA) are available upon request, detailing key parameters such as assay, impurity profile, and physical characteristics. We adhere to cGMP principles where applicable to support our clients in regulated research and development.

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 to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases and reducing agents.
