Quality Control

Our 1-Hexen-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 and assay. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, preferably at 2-8°C or under refrigeration as specified. Keep away from heat, sparks, open flames, and oxidizing agents. Containers should be kept tightly sealed and upright to minimize loss and degradation.
