Quality Control

Our 1,3-Dichloro-2-Butene is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including gas chromatography (GC) for assay and impurity profiling, to meet exacting customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full traceability and compliance with your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C (refrigerated) for long-term stability, although short-term storage at controlled room temperature (15-25°C) is acceptable. Keep away from strong acids, bases, and oxidizing agents.
