Quality Control

Our Ethyl 3-(Methylamino)-2-Butenoate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (IR, NMR), to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to guarantee 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 area at 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.
