Quality Control

Our production of 3,3',3'',3'''-[[(3-Hydroxypropyl)Imino]Bis(Ethylenenitrilo)]Tetrapropanol adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing to ensure consistency, purity, and compliance with agreed specifications. A Certificate of Analysis (COA) detailing key parameters such as assay, identity, and impurity profile 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, 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 after each use to prevent absorption of atmospheric moisture. For long-term storage, consider using an inert atmosphere to minimize potential oxidation.
