Quality Control

Our 2,2'-Dibromodiphenylacetylene is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specification results. Our quality commitment ensures the material meets the high standards required for sensitive synthetic applications in research and development.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
