Quality Control

Our N,n-Bis(3-Aminopropyl)Methylamine is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets precise specifications for industrial and fine chemical applications. Certificates of Analysis (COA) detailing purity, physical properties, and test results are provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide, which can affect product quality. Keep away from heat, sparks, and open flame. Store away from strong acids and oxidizing agents.
