Quality Control

Our Ethyl(E)-4-Chloro-3-Methoxy-2-Butenoate is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC and GC analysis, to ensure the 97% minimum purity specification and identity are met. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical properties is provided with each shipment to guarantee traceability and compliance with your research or production standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. This material is moisture-sensitive (hygroscopic) and should be handled under an inert atmosphere for prolonged storage to maintain stability.
