Quality Control

Our Benzene, 3-Buten-1-Ynyl- (9Ci) is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets the high standards required for research and synthesis. A Certificate of Analysis (COA) detailing specific results for purity, identity, and impurities is provided with every shipment to guarantee traceability and consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended long-term storage temperature is 2-8°C. Keep away from heat, sparks, and open flames. Due to its sensitivity, allow the container to reach ambient temperature before opening to minimize moisture ingress and degradation.
