Quality Control

Our 2,4-Nonadecadiynoic Acid is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing, including purity assay and identity confirmation, to ensure it meets the high standards required for research and development applications. A Certificate of Analysis (COA) detailing specific results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
