Quality Control

Our (Z)-3-Undecen-5-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. A Certificate of Analysis (COA) detailing all test results is provided with every shipment 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) at 2-8°C to minimize oxidation and degradation due to its highly volatile and easily oxidized nature. Keep away from heat, sparks, and open flames. Allow the container to reach room temperature before opening to prevent moisture condensation.
