Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is analyzed to confirm identity, purity, and impurity profile. Certificates of Analysis (COA) documenting key parameters are available upon request. We adhere to strict quality management protocols to ensure batch-to-batch consistency and reliability for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from strong acids and incompatible organic solvents.
