Quality Control

Our 1-Chlorobuta-1,3-Diene is produced and handled under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including purity assay and impurity profiling by GC and GC-MS, to ensure it meets the high standards required for synthetic applications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and reactive nature, store in a cool (recommended 2-8°C), well-ventilated area, away from heat, sparks, and open flames. Keep container tightly sealed under an inert atmosphere (e.g., nitrogen) when not in use to prevent polymerization and degradation. Observe all local regulations for flammable and reactive chemicals.
