Quality Control

Our 2-Ethylbutyryl Chloride is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including assay, purity profiling, and identification, to ensure it meets the high standards required for industrial and research applications. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and incompatible materials such as strong bases, alcohols, and oxidizing agents. Due to its hygroscopic and moisture-sensitive nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen) to maintain product integrity. Recommended storage temperature: 2-8°C for long-term stability.
