Quality Control

Our 2,4-Hexadiyne is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation. A Certificate of Analysis (COA) detailing specific results for purity, identity, and relevant impurities is provided with every shipment. We support compliance with global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (typically 15-25°C). Keep away from heat, sparks, open flames, and incompatible materials such as strong oxidizing agents. Due to its nature as a reactive alkyne, it is recommended to store under an inert atmosphere for long-term stability and to minimize the risk of polymerization.
