Quality Control

Our (2E)-4-(Dimethylamino)-2-Butenoic Acid Ethyl Ester is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request to support your quality assurance and regulatory compliance needs.

Storage

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