Quality Control

Our Sodium Bis(5-Oxo-L-Prolinate) is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting results for assay, chiral purity, heavy metals, and residual solvents are provided with every shipment to guarantee traceability and compliance with customer requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect quality and performance.
