Quality Control

Every batch of 3-Penten-2-One, 3,4-Difluoro-, (3E)- is produced and analyzed under strict quality management protocols to ensure consistency and purity for research and development applications. Our standard grade meets high-purity requirements for synthetic chemistry, with comprehensive testing including identity confirmation, assay, and impurity profiling. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical quality attributes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its reactivity as a strong acid/organic solvent, keep away from incompatible materials such as strong bases, oxidizing agents, and reducing agents. Containers should be kept tightly sealed when not in use to prevent degradation.
