Quality Control

Our 4-Pentenoyl Chloride is manufactured under strict quality management systems. Every 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 research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with each shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and reacts vigorously with water, strong bases, and oxidizing agents. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term stability.
