Quality Control

Our (2-Hydroxyethyl)Trimethylammonium 5-Oxo-Dl-Prolinate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for assay and purity, to ensure it meets stringent specifications. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment. We support compliance with cGMP and REACH requirements for global supply.

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 nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect stability and handling properties.
