Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized to confirm identity, purity, and consistency. Certificates of Analysis (COA) documenting key parameters are available upon request. We adhere to a cGMP-compliant quality management system to ensure reliability for your critical R&D and production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic nature, the container must be kept tightly sealed in a low-humidity environment to prevent moisture uptake. Recommended storage temperature is 15-25°C.
