Quality Control

Our n-Isononylpropane-1,3-Diamine is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and titration methods, to ensure consistent purity and meet precise specifications. A comprehensive Certificate of Analysis (COA) detailing assay, water content, color, and other critical parameters is provided with each shipment to guarantee compliance with your process requirements.

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). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent moisture absorption and degradation. Keep away from heat, sparks, open flames, and strong oxidizing agents.
