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 and impurity profiles. We adhere to a cGMP-compliant quality management system to guarantee reliability for research and industrial 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 sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials.
