Quality Control

Our 1-Nonen-4-Yne is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis including GC, GC-MS, and NMR 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, well-ventilated place, away from heat, sparks, and open flames. Due to its highly volatile and easily oxidized nature, it is recommended to store at 2-8°C for long-term stability. Keep container tightly sealed when not in use to prevent evaporation and degradation.
