Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is characterized using advanced analytical techniques to confirm identity, purity, and composition. Certificates of Analysis (COA) detailing specific results for purity (by HPLC), amino acid analysis, and other relevant parameters are available upon request. We adhere to GMP principles for handling high-value research chemicals to ensure batch-to-batch consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed in a desiccated environment to prevent degradation. For long-term storage, consider storing under inert atmosphere at lower temperatures (-20°C).
