Quality Control

Our 1-Cycloocten-5-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 techniques including GC, HPLC, and NMR to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical properties is provided with every shipment. We support custom purity grades to meet specific research and development requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C or as specified on the label or COA. Due to its reactive nature, keep away from strong oxidizers and ensure the container is kept tightly sealed in a cool, dry, and well-ventilated place.
