Quality Control

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

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases, amines, alcohols, and oxidizing agents. Due to its hygroscopic and moisture-sensitive nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature is 2-8°C for long-term stability.
