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) documenting key parameters are available upon request. We adhere to a cGMP-compliant quality management system to guarantee reliable supply for demanding industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from incompatible materials such as strong oxidizing agents. Due to its light-sensitive nature, containers should be kept in opaque packaging or dark storage conditions.
