Quality Control

Our (Z)-5-Undecen-3-Yne 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, purity, and isomeric composition. Certificates of Analysis (COA) detailing all test results are provided and available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place. Due to its highly volatile and easily oxidized nature, the container should be kept tightly sealed and away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C for long-term stability.
