Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized using advanced analytical techniques including HPLC, NMR, and mass spectrometry to confirm identity and purity. Certificates of Analysis (COA) are available upon request, detailing batch-specific results for key parameters such as assay and impurity profiles. We adhere to a cGMP-compliant quality management system to ensure traceability and consistency for research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat and incompatible materials.
