Quality Control

Our Benzene, 1,4-Pentadiynyl- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay (by GC or HPLC), identity confirmation (by IR and/or NMR), and impurity profile. Our quality commitment supports research and development where reliable purity and batch-to-batch consistency are paramount.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong oxidizing agents.
