Quality Control

Our 1-Dodecen-3-Yne is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (NMR, IR), to verify identity, purity, and the absence of critical impurities. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory needs.

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 area at room temperature (15-25°C). Due to its properties, it is easily oxidized and should be kept away from strong acids and oxidizing agents. Keep the container tightly sealed when not in use to minimize exposure to air and moisture.
