Quality Control

Our Dl-Methioninol is produced under a strict quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including HPLC/GC purity, chiral purity, and residual solvent analysis, to meet the stringent requirements of pharmaceutical and research applications. A Certificate of Analysis (COA) is provided with each shipment, and custom specifications can be developed to align with your specific project needs.

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 and easily oxidized nature, it is recommended to handle under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to minimize exposure to air and moisture during use.
