Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized using advanced analytical techniques to confirm identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay (HPLC), related substances, and residual solvents are available upon request. We adhere to a cGMP-compliant quality management system for production, ensuring reliability for research and scale-up applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and easily oxidized; containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to maintain stability and purity. Keep away from heat and incompatible materials.
