Quality Control

Our Ethyl 2-Isocyanato-4-(Methylthio)Butyrate is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with each shipment to support your quality assurance and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and amines.
