Quality Control

Our 4-(Diethylamino)Butylamine is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and titration methods, to ensure high purity and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, identity, and impurity profiles. Our quality commitment ensures the material meets the specifications required for reliable performance in your synthesis and production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture and carbon dioxide. Keep away from strong acids and oxidizing agents.
