Quality Control

Our Ethylidene 2-Butenoate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing specific results for purity, identity, and impurities is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled 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.
