Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Quality is assured through multiple analytical checkpoints including identity confirmation, purity assay, and impurity profiling. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality management systems.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product performance and stability.
