Quality Control

Our Isophorondiamine is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and titration methods, to ensure it meets precise specifications for purity, color, and moisture content. Certificates of Analysis (COA) are provided with each shipment, and we can support compliance with relevant global regulatory frameworks such as REACH.

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 contact with atmospheric moisture and carbon dioxide, which can affect product quality.
