Quality Control

Our 1,9-Decadiyne 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 GC, GC-MS, and NMR, to verify identity and purity. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality parameters. We adhere to relevant ISO standards to support our commitment to reliable supply and product integrity for your research and development needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place at temperatures between 2°C and 8°C (refrigerated conditions) or as specified on the label. Keep away from heat, sparks, and open flames. Use appropriate explosion-proof equipment. Containers must be kept tightly sealed when not in use to prevent evaporation and potential concentration of peroxides.
