Quality Control

Our L-Methionine, 1-Methylethyl Ester is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity verification and impurity profiling, to ensure it meets the high standards required for pharmaceutical and research applications. Certificates of Analysis (COA) with detailed chromatographic data (HPLC, GC) are provided to guarantee consistent quality, identity, and purity.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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.
