Quality Control

Our 4-(3-Ethoxyanilino)-4-Oxobut-2-Enoic Acid is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the precise requirements of our clients in research and manufacturing. A Certificate of Analysis (COA) detailing all specifications and test results is provided with each shipment.

Storage

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