Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is characterized using advanced analytical techniques to guarantee identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for purity, impurities, and other critical parameters are available upon request. We adhere to strict quality management protocols to support our customers in research, development, and scale-up activities.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong acids and incompatible organic solvents.
