Quality Control

Our n-Formyl-Dl-Ethionine is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing including HPLC for purity, spectroscopic identification (IR, NMR), and determination of critical parameters like optical rotation and moisture content. We provide full traceability and Certificates of Analysis (COA) are available upon request to ensure compliance with your research or production specifications.

Storage

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