Quality Control

Our 1-Chloro-1-Butene is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) for purity and identity verification, to ensure it meets precise customer and industry specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids and strong oxidizing agents. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use. Recommended storage temperature is 2-8°C for extended stability.
