Quality Control

Our 3-Hexen-1-Yne is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced chromatographic and spectroscopic techniques (GC, GC-MS, NMR) to confirm identity and quantify purity. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with every shipment, ensuring full traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and reactive nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place. Recommended storage temperature is 2-8°C to maximize stability. Keep away from strong acids, oxidizers, and sources of ignition.
