Quality Control

Our 2,2'-Methylenebis(Cyclohexanamine) is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, impurity profiling, and physical property verification, to ensure it meets precise customer and industry specifications. Certificates of Analysis (COA) documenting purity, color, moisture content, and other critical parameters are provided with every shipment to guarantee supply reliability and batch-to-batch consistency.

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). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide, which can affect product quality.
