Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Quality is verified through analytical methods including HPLC, UV-Vis spectroscopy, and titration. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles 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 place. Due to its strictly light-sensitive and hygroscopic nature, this material must be handled under conditions that minimize exposure to ambient light and atmospheric moisture. Recommended storage temperature is 2-8°C for long-term stability.
