Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and customer-specific requirements. Each batch is analyzed to confirm identity, purity, and key physical parameters. Certificates of Analysis (COA) documenting these results are available upon request. We adhere to a robust Quality Management System to guarantee batch-to-batch consistency and supply reliability for our global partners.

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/59-77°F). Due to its hygroscopic nature, the container must be kept tightly sealed to exclude moisture. Keep away from strong acids and incompatible organic solvents.
