Quality Control

Our Dihydroxy(5-Oxo-L-Prolinato-N1,O2)Aluminium is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with key parameters including assay, impurity profile, and physical characterization. Specifications can be aligned with customer requirements for research, pharmaceutical development, or industrial use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
