Quality Control

Our Henicosanedioic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) detailing purity, physical characteristics, and test results is provided with each shipment and is available upon request.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality. Keep away from strong oxidizing agents.
