Quality Control

Our production of 3,6,9,12-Tetraoxatetradecanoic Acid, 14-Hydroxy- adheres to stringent quality management protocols. Each batch is analyzed using advanced techniques like HPLC, GC, and NMR to ensure high purity and consistent composition. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your specifications.

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 sealed under dry conditions to prevent absorption of atmospheric moisture, which can affect product quality.
