Quality Control

Our Phenylundecanoic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets the high standards required for industrial and research applications. A Certificate of Analysis (COA) detailing specific results for purity, appearance, and other critical parameters is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
