Quality Control

Our 5-Undecenoic Acid is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing specific results for purity, assay, and relevant impurities is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). As a strong acid/organic solvent that is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation to maintain optimal purity and prevent degradation. Keep away from heat, sparks, and open flames.
