Quality Control

Our Heptacosane-1,27-Dioic Acid is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay by titration or HPLC, identity confirmation (IR), and impurity profiling, to ensure it meets exacting specifications for research and industrial use. A Certificate of Analysis (COA) detailing purity, physical characteristics, and test results 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 a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect purity and performance.
