Quality Control

Our 4-Chloro-2-Pentenoyl Chloride is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including assay (HPLC), identity confirmation (IR, NMR), and impurity profiling, to ensure it meets the high-purity standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and classification as a strong acid/organic solvent, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, open flames, and incompatible materials such as bases, alcohols, and oxidizing agents.
