Quality Control

Our (E)-3-Tridecen-1-Yne is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including GC, GC-MS, and NMR, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, confirming compliance with agreed specifications. For research and commercial applications requiring specific purity grades (e.g., >95%, >98%), please contact our technical team.

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. Recommended long-term storage temperature is 2-8°C. Due to its easily oxidized nature, minimize exposure to air during handling and sub-sampling.
