Quality Control

Our Pentachloro-3-Butenoic Acid Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including assay, purity profiling, and identity confirmation, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each 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). This material is hygroscopic (moisture-sensitive) and reacts with water; ensure containers are kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from strong bases, oxidizing agents, and sources of ignition.
