Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and customer-specific requirements. Each batch is analyzed using advanced techniques like HPLC, GC, and NMR to verify identity, purity, and the absence of critical impurities. Certificates of Analysis (COA) are available upon request, providing full transparency and traceability for your quality assurance processes.

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 (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and performance.
