Quality Control

Our production of 3,6,9,12,15,18,21,24,27-Nonaoxaoctacosanoic Acid adheres to stringent internal quality standards to ensure batch-to-batch consistency and high purity. Each lot is characterized using advanced analytical techniques including NMR, HPLC, and titration methods. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment and is available upon request.

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 and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize moisture uptake.
