Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for research and manufacturing. Each batch is analyzed using advanced techniques like HPLC, NMR, and mass spectrometry to confirm identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
