Quality Control

Our 1,1,7,7-Tetramethyl-4-Phenyldiethylenetriamine is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets exacting specifications for catalytic and synthetic applications. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and consistency for our global B2B clients.

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 tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation from moisture and oxidation. Keep away from strong acids and oxidizing agents.
