Quality Control

Our 2-Vinyl-2-Butenal is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay by GC or HPLC, identity confirmation (IR), and impurity profiling, to ensure it meets the high-purity standards required for synthetic applications. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place. Due to its highly volatile and easily oxidized nature, the container should be kept tightly sealed and away from heat, sparks, and open flames. Recommended long-term storage temperature is 2-8°C.
