Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and customer-specific requirements. We implement strict in-process controls and final release testing, which may include assays for purity and identity confirmation. Certificates of Analysis (COA) are available upon request to provide full transparency and traceability for each batch.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (typically 15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
