Quality Control

Every batch of (E)-5-Tetradecen-3-Yne is produced and tested under a strict quality management system to ensure consistency and reliability for your synthetic processes. We provide comprehensive analytical data, including GC, HPLC, and NMR analysis, to verify identity, purity, and isomeric composition. A Certificate of Analysis (COA) is available for each lot, detailing all relevant specifications and test results.

Storage

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