Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for research and diagnostic use. Each batch is characterized for purity, identity, and stability. Certificates of Analysis (COA) detailing specific test results, including assay by UV-Vis spectroscopy and identification by electrophoresis or chromatography, are available upon request. We adhere to a quality management system to guarantee batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C. This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). For long-term stability, consider storage at -20°C. Allow the product to equilibrate to room temperature before opening to prevent condensation.
