Quality Control

Our 4-Chloro-3-Oxobutyryl Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent decomposition. Keep away from strong bases, oxidizing agents, and sources of ignition.
