Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Quality is verified through analytical techniques including GC, HPLC, and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from incompatible materials such as strong acids and bases. Recommended long-term storage temperature is between 2°C and 8°C. Keep container tightly sealed when not in use to prevent moisture absorption and volatilization.
